I tracked down the dragons from the Adept's mountain (in my miniature dragon form) and successfully made contact. I offered to lead them to the females I set up earlier in return for an alliance. They cautiously accepted and are now there and on call should I need them.
When I returned, I was given a blood test to determine my heritage. Apparently, it is now confirmed that Caine is my biological father. No news on my mother, but she was likely chaosian given my shapeshifting abilities. I'm still trying to decide how I feel about the whole having a father thing. I guess I will take it a day at a time.
I returned to investigate the brains in the basement. One had a hint of Pattern essence to it but it was deep in dream. I hauled it out and slowly woke it up to find out who it is. The answer turned out to be another uncle I was unfamiliar with, a fellow named Delwin. He was captured while spying for Oberon a long time ago and was pretty behind on current events. He does not seem to be nuts, so we accelerated his regrowth as much as we could. He is a shapeshifter, so he will recover much quicker than Thera.
