I’d say the illithid one is ready to go. I’ll share all the queries with you again one more time before I send them.

Yeah, that sounds like a good idea. So to summarize, and add a few more ideas...
Energy guy: resistance or immunity to positive and negative energy, energy charge (from MM3 glossary, bestows positive levels, wasn't used by anyting in the book) and energy drain abilities.
Transitive guy: ethereal jaunt as Su ability (like ethereal filcher and marauder), similar abilities for astral travel and shadow walk, spell-like abilities related to these planes.
Portal guy: These guys could double as sentinels for an additional role, since the rilmani homeplane is the hub of the multiverse. Give 'em planar attunement, spell-like abilities related to portals and planar travel, defensive stance, immunity to the negative effects of the River Styx (Oceanus seems harmless), and abilities to sense and/or control planar breaches.

These are the rilmani agents for the energy planes (Positive and Negative). They are immune to the effects of these planes, and can use positive energy charge and negative energy drain attacks.

Outsider, CR 10
These are the rilmani agents on the transitive planes (Astral, Ethereal, Shadow). They can use ethereal jaunt, astral travel, and shadow walk at will, and have spell-like powers related to these planes.

Outsider, CR 15
These rilmani are guardians of the pathways between planes, serving as sentinels for the portals and planar breaches of the multiverse. They patrol the Outlands, and places such as the Rivers Styx (they are immune to its effects) and Oceanus, Mount Olympus, and Ygdrassil (sp?). They can sense and control planar breaches, and have the ability to close and open portals (permanently if desired).
All rilmani have physical weapons that they attack with, and most have a unique supernatural attack form.
One way to take care of the names and appearance at the same time is to assign metallic appearances. We have the Cuprilach (cuprum, copper), Argenach (aregentum, silver), Aurumach (aurum, gold), Ferrumach (ferrum, iron) already, for example.
Other metals, such as Mercury, Zinc, Aluminum, Titanium, Nickel, Cobalt, etc could be used.

In the meantime, following your lead, I checked a latin dictionary and the periodic table...
Hydrargyrnach (mercury)
Stannumach (tin)
Wolframach (tungsten)
Stibiumach (antimony*)
Alumenach (aluminum)
Sulphurimach (sulfur, "brimstone")
Titanach (titanium)
Eletrumach (electrum)
Zincumach (zinc)
Orichalcumach (brass)
Aeneusach or pyropusach (bronze)
*In case you didn't know what antimony is (I didn't): The stable form of antimony is a blue-white metal.
Oddly, the abiorach doesn't fit this format.
true on the abiorach.. and the plumach? The names don’t have to be metallica (hehe), but that does make it easier.

I’ll think on this at home, as I’m just posting and leaving.
Let’s get the faerie query (heehee!) underway.
In the Creature Catalog, we have (smaller than Medium, of course!):
Asrai, Atomie, Booka, Bramble, Brownie, Buckawn, Dobie, Ekrat, Faerie Fiddler, Flitterling, Frost, Gorse, Killmoulis, Leprechaun, Nightshade, Quickling, Squeaker, and Stwinger.
And that's just what we have done so far!
this thread has a lot more hints on conversions, and ideas for real world legends we could convert.
And we definitely need some more malevolent fey... (bramble, nightshade, and quickling are a nice start)
