BECMI... S! Sidereal Rules
Since I'm sitting here at an auto-repair shop getting my brakes fixed, and will be for another couple of hours or so, now seems like a perfect time to post the next update in this thread. I should note here at the outset that these rules were never tested in actual play- the game I ran that ended in the Transcendence of most of the PCs never saw said PCs get beyond the level of Incarnations (half were DR 48, the other half DR 37 or 38, but the difference in terms of raw power was largely meaningless for the events they got involved in).
Back during the days of 1st Edition AD&D, when I was expanding on the "gold box" Immortals Rules of "basic" D&D, I didn't have much concept of things like "game balance" or "realism-" having never actually played an Immortal directly, I just figured that if my new "Old Ones" and "Originals" rules looked pretty similar to the existing Immortals rules, then they'd probably work. Among other things, this meant that I'd need to set up a rigid and well-defined hierarchy in each of those tiers of existence, since the Immortals had a well-defined one (there are five tiers of Immortal, each with five "grades" within it, and a hard limit on the number of beings in the multiverse that can hold each grade and tier).
There's no need in the modern age to go into the details of the hierarchy I came up with for the Old Ones or Originals, except to note the fact relevant to the system I came up with for incorporating the IH Sidereals into my grand setting described in this thread: the fact that there were nine "grades" of Old One altogether. Essentially, I divided them into three tiers, the newbies/peons, the middle managers, and the rulers (those aren't the actual names I used, just the concept I followed), and within each tier, three grades: Low, Middle, and High. Nine total. Immortals in the BECMI system have "Power Points" which are effectively agglomerations of XP, and determine what the tier and grade of each individual is; I gave the Old Ones "Life Points" which served the same function within their society and could be used for actions just as Immortal PP could be (though the Old Ones would obviously be capable of far better and more powerful stuff with their LP).
For the Originals, I created a similar hierarchy which is even less relevant today, since back when I was coming up with all this I really had no clue what the Originals actually were or did in their own wide vista of existence external to the "Incomplete Creation" that was the setting including the Voidsphere and Chaos and multiverses. The Originals, too, had their own set of "Creation Points," which placed them within their hierarchy and could be used to power their own unique abilities- though I had no idea what such beings might do and never actually defined any uses for these CP.
In light of the fact that I'd divided the Old Ones into three main tiers, I found it highly significant that UK in his IH rules divided the Sidereals in just the same way. The fact that I had three further subdivisions within each tier just meant that in order to slot the IH concepts into my old rules and setting, or vice versa depending on how you look at it, all I had to do was take the basic IH templates and apply each one in triplicate (more or less).
Where my original scheme really differed from the IH was the idea of Life Points; the IH doesn't differentiate Sidereals from Deities at all except for the raw number of Divine Ranks each has. But I kept the idea of Life Points alive just the same: I decided that since gods were measured by Divine Ranks, and each DR granted the critical measure of divine power that is a Divine Ability, I could bring the LP idea into the new era by giving my Sidereals "Cosmic Ranks" which would each grant a Cosmic Ability. Of course, the acronym "CR" carries a rather different and important meaning within the modern game system, so I clearly had to use a different one for my Sidereals; therefore, I adopted UK's convention of calling the greater setting the "Kosmos" just far enough to refer to this new "Sidereal rank" concept as the Kosmic Rank, or KR.
One convenient thing this concept of separate KR afforded me was the notion that DR could now be entirely separated from it; I could set a cap on DR if I liked, and it wouldn't have to affect the advancement of Sidereals at all- I was already treating the DR in my system as a parallel set of "levels" which operated in tandem with the base system of HD and XP, so logically I could now do the same with KR and Cosmic Abilities operating in tandem with DR and Divines. I played with several schema and limits of each quality, before arriving at the Table. I'll copy the section intended to represent the first of the three tiers below:

These beings would all be classed as Elder Ones in UK's system. The basic concept here is that Overgods are Sidereals of demiplanes, Cosmic Stewards are Sidereals of very large demiplanes, or even whole planes that have specific limits (for example, planar layers in the Outer Planes), and Planemasters represent very large to truly infinite planes (but still just represent single planes rather than multiple ones). I decided not to keep the name "Elder One" for any of these three, since I was already using the term "Elder" specifically to refer to the gods who were greater than Greater but less than Incarnations.
Where this gets somewhat troublesome, comparing to the IH, is that the basic Elder One template is actually even less powerful (in some ways) than the Incarnation template I used for my deities of 37-48 DR! It is therefore not entirely appropriate to use the IH Elder One template for my Sidereals, but it can be used as a base at least. In particular, they'd have the d100 HD, max hit points, Maven+Omnicompetent, and all the base Cosmic powers that just come with Sidereal territory (Cosmic Consciousness, Cosmic String, etc.). Regardless of status as Overgod, Steward, or Planemaster, these beings all get every single bonus Cosmic Ability their primary Portfolios grant at the Elder One level- since they are in fact Sidereals, Cosmics are not esoteric the way they are to deities, and the one-Esoteric rule now applies to Transcendental Abilities instead. Sidereals are not limited in the number of Portfolios they can hold, but in practice each one wouldn't want very many since the Portfolios carry weaknesses in addition to powers (and the weaknesses tend to add up- particularly the number of artifacts that can defeat the entity's Cosmic String).
The significant difference is in the divine bonus each one gets: my Sidereals have a lot more DR than UK's. Not only that, but they also have KR to deal with. So here's how that changes in each template: you just apply the basics of what each DR grants (+1 divine bonus to everything, +2 to all six ability scores, 1 Divine Ability or 6 feats or 1/6 of a Cosmic, and +5 Level Adjustment), and do it for all DR the entity you're building has. You then apply similar bonuses for each KR the entity has: each KR grants a +6 divine bonus to everything, +12 to all six ability scores, 1 Cosmic Ability (or 6 Divines or 36 feats), and a +30 Level Adjustment. Once you have all that figured out, you can get the being's CR by just multiplying the HD+Level Adjustment by 2/3 (exactly as UK does, if you check the math on his templates).
Armed with the knowledge of just what each DR and KR gets you, you can then apply it to the next two IH templates, the Old One and First One. My table for the second-tier Sidereals:
Old One (85 DR, 4 KR): 4000 HD, 100,000,000,000,000 QP.

My concept of beings at this stage of existence is that they're sort of "meta-waves" that form basic, underpinning laws of physics that clusters of planes base themselves upon, sort of like a field of ground (the second-tier Sidereal) allows trees (individual planes/demiplanes, or first-tier Sidereals) to grow. Old Ones would be planes containing lots of demiplanes, sort of like the official 3.5E conception of the Abyss, or just planes containing small clusters of sub-planes like the primary Elements are linked to the Paraelemental, Quasielemental, and Demielemental planes. Outer Gods (yes, the link to Lovecraft is intentional) would be much larger planes, like my setting's Heaven or Abyss, or Transitives which are linked to lots of other planes (such as the Ethereal or Astral Plane). Conceptuals are a slightly more difficult concept, because here we start to go beyond the idea of planes entirely: Conceptuals are supposed to be basic principles that apply to all planes, or at least potentially apply to them. Conceptuals are a sort of intermediate stage between Sidereals-as-planes and Sidereals-as-derivative-underpinnings-of-Reality which the third tier represent. Conceptuals could be Sidereals for entire Cosmoses at once, or perhaps (in Fate's "pure" cosmos, for example) divisions of a cosmos which could be considered whole multiverses in their own right. Conceptuals can also be base ideas such as "Magic" or "Love" that exist just about everywhere, but are not directly associated with any specific plane or set of planes- but which are not quite large or important enough to get the being up into third-tier territory.
Regardless of grade, the second-tier Sidereals all use the Old One IH template, with the usual adjustments for DR and KR, and they get all the appropriate Cosmic Abilities from their primary Portfolios. The only Portfolio abilities they do not get are the bonus Transcendentals given to First Ones.
And speaking of those, time to copy the Table for the third-tier Sidereals:
Relational (120 DR, 11 KR): 10000 HD, 100,000,000,000,000,000 QP.

Fundamental (120 DR, 25 KR): 30000 HD, 80,000,000,000,000,000,000 QP.
----------------------------------------------------------------------
Again, the dividing line exists between these pinnacle-of-their-tier beings and the next stage of existence, the Eternals/Originals. My concept of First Ones is that they can be thought of both as avatars/emanations of the Demiurge that have forgotten what they are, or are intrusions from another Reality (these would be Anomalies in the IH canon), or even that they are beings which have grown to become so important in Reality as a whole that they can rewrite rules across almost every part of it. That's what a First One is: a basic principle of physics that is so deeply ingrained, so intrinsic to the functioning of Reality, that every single set of laws of physics that exists in any cosmos (or even no cosmos, if a layer in the Far Realm) needs to use it or refer to it. The differences between the three types are largely academic to any lesser being: these are the true movers and shakers of any Reality before the Demiurge wakes up. They use the First One template, and get the First One-level bonus Transcendentals from their double-primary Portfolios. The template has the usual adjustments for DR and KR, but note the important point about DR particularly: I applied a hard cap on DR here. No entity, no matter how powerful, can have more than 120 DR in my scheme- to advance further you have to do it with KR or something else.
What might that "something else" be, you ask? That seems like a good topic for the next post.
