ahh ok i was just makeing sure that we werent barking up the wrong tree by not giving him any. Could we do an "As an Obyrith" little Blurb at the end sense he makes somewhat sense as one of those critters. That way is someone wants him to be one they can.
Frankly, I'd rather either give him the subtype or not give him the subtype. Adding an "As an Obyrith" subentry wouldn't seem to add much.
Besides, it's the powers that are important, not the Subtype. We should be asking ourselves "Do we want Ythog-Nthlei to drive people mad who look at it or not?"
There are a couple of madness-causing objects in the adventure - glyphs on an onyx pillar in
Room 20 that can turn the reader "irrevocably lawful evil" or "permanently insane", and an interdimensional portal in Room 23 in which can appear "The Eye of Zoth Ommog" that can cause a victim to "die permanently" or "succumb to a random insanity".
Zoth Ommog is an entity mentioned in both of those madness-causing objects, so it seems more likely
he's the one with the insanity inflicting appearance rather than Ythog-Nthlei.
Maybe there's a clue in the titles?
The glyphs in
Room 20 include the following:
“During the ninth rotation of our galactic cluster in this the 34321st year of our Master’s reign, we, the remaining children of the Great Lord Ythog-Nthlei do hereby register and sanctify this, our Holy Base. From these divine depths we shall build and grow until we have enough strength to release our Father, Zoth Ommog, from his imprisonment beyond the curtain of time.”
The apparition in Room 23 gives the following warning:
“We have at last imprisoned the Dark King, Ythog-Nthlei, here beneath his very base. The process cost more than we could have believed in time and lives. For over 200 years our brotherhood of magicians has struggled to prevent these sons of the old ones from releasing their horrible sires. Now only a few of us remain, but the task is complete. This image is a warning. Do not, under any circumstances, attempt to enter the chamber beyond this door. Any transgression into the area will release the King from his bondage, and will surely spell your doom.”
So, Ythog-Nthlei has the titles "Dark King" and "Great Lord" and his cult seeks to release "Father Zoth Ommog" from an extratemporal prison.
