I sometimes have a hard time making the Transcendentals anything more than Ye Olde Enigmatic AIs. I feel like they should all be distinct - merging them together the the Aia thing, not what the Transcendentals are going for. The T's should have some personality. Here are a few "models" that I've used for them to give them a bit of personality. When I have more than one involved they tend to come in threes.
Mrs. Whatsit, Mrs. Who, and Mrs. Witch from A Wrinkle in Time. You need a stock of quotations fro Mrs. Who, though you can occasionally pull one from the adventure that they're currently entering - it's a wonderful thing when a player recognizes a phrase pulled wholesale from the future.
Brahma, Vishnu, and Shiva from Hindu mythology. Those gods themselves don't have much personality, at least to me, but they at least have distinct jobs. This also brings up the idea of an "avatar" of the Transcendentals, which links into the Keats persona from Hyperion, but that's a different thread entirely.
The Fates. This provides a little distinction in terms of personality and age (the latter of which will be weird to some of the PCs). It also gives the job breakdown: one hires the characters, one deals with them on a day-to-day basis, and one… well…
