D&D 3.5 has a Monster Manual which provides the most details for Thoon. There's a decent YouTube video out now as well. The rest is up to your imagination. I chose to tap into Lovecraft, since the Far Realm and madness are supposed to be attributed to Thoon.
Ultimately, leaving things cryptic makes it all the more unnerving for players, so have fun!
Anybody got a good direction to look?
I presume you have read Volo's already? If you haven't that has some info on mind flayers.
