OH YEAH!
Tzarevitch has the right idea!
In my campaign of 5 years-
Kalak dead...body never found. His son Darque is doing all he can to control the council and they don't even know he exists
Bane and Valentine. SK that are of my creation. Bane is being used in my Story Hour. He has a secret underground city on the esturary on an island. Valentine is a twisted piece. She was cursed by Rajaat and thus flickers in and out of time. Hard to control the world when you might be sent forward again and need to restart from scratch.
Albech-Re is possibly my favorite. The "B--ch" as my players refer to her as is a sex crazed paranoid with waaaaay too much power. As you did, she has a clone that is in hiding. I have an anti-V Alliance group called the Tembo Society. These folks are looking to overpower the SK but to create freedom- but for the sheer power of it. Three Kairshargas and two T'lizes were planning on taking over Raam. The SQ knew this and used her "death" to draw them out. Thus the "diseased wind" that went through the city at her "death."
Didn't get to the others. I did fleshout the cities a bit. Draj's Moon Priests are scarey. They are psionic templar assassins that use tatooing to symbolize level of power.
For Avangions, there is Korgunard (killed later per the adventure), the Redeemed One (won't say whom so as not to spoil it for any not in the knowing) and Hope. Hope is an Avangion hiding in the Hinterlands trying to build a city to live in peace. I have another character, Daina, whom is 20 pre/20 psion trying to become an Avangion. So far no one is willing to aid her in furthering her development due to her goals. She thinks the V Alliance needs to take the war to the SK and has read about the Preserver Knights (Paladins from the Green Age) which she wants to reconstruct (hard when the gods have left...but will they return...?)
