While I would certainly run this as an immortal son of a goddess, I would also make full use of the red herrings provided to thoroughly confuse my players. Especially if they had a stake in whatever possible changes might be coming and need to discover if Jaith is merely a messenger or an active participant.
Overall, I think this is an excellent idea. This is an intriguing race, just alien enough to make interacting with them interesting and quirky.
I would also like to see some detail about how the eye color and affinity aspect works. Perhaps some concrete examples?
What sort of advice are you looking for in order to take it out of Advice Requested?
I can see a few possible uses for this.
First, a player agrees to start out with an insane character, someone who just finished up their time as a goat. It can be tricky, but having a character who is mad can add all sorts of fun and complications to a story.
Second, what do the players do when they discover that their bounty (who must be captured alive) has been turned into a goat? Especially if their employer is not the forgiving type.
I would love to see how players deal with trying to get close enough to examine an artifact that has such a nasty effect based solely on proximity.
I am always impressed when someone can base a culture around one central thing, such as glass, and have it come out feeling internally consistent and really creative rather than forced. This is well done. I can't wait to read the related Ouzquin Dremorix subs.
There's enough detail here that I can really visualize the culture and their tools.
Another gem. A horrid, disgusting, assault of evil and madness upon the senses; a fruitful method of tormenting heroes; a vision into the mind of the insane. That kind of gem :)
I must find some way to use this! Such a twisted spout of creativity must not be wasted.
5/5 and an HoH.
