From the cannon SMs, here’s a short list of current states/how they got there in my campaign that may assist.
Borys - Not directly killed by Rajaat, but instead one of his swords, contingency spell from before he was a champion kicked in, he became a wraith and got stuck in the body of a half-elf female. Currenty trying to get out of the demihuman body, return to dragonhood, and gather the remnants of his city/outposts.
Kalak - Still dead (maybe), body is still missing and hasn’t been found.
Tek - Dead, but a copy of his mind inhabits his throne and the longer his “son” sits on it the more control it has.
Dregoth - Failed his bid to become a god but was transformed into a living dragon. Freed from his undead mind lock he’s reassessed the world and is actively recruiting Dray, restoring his old city, and spreading the word of a return to the Green Age. He’s harnessed many Tyr storms and is slowly refilling the bay.
Hamanu - Still running Urik, trying to reconcile the return of Sielba and all the other changes going on while staving off his metamorphosis.
Abalach-Re - Killed by a part of the sword, she was reborn into the first child born to her line and is now rapidly aging and gathering her power. She’s hiding out with control of a single village far from Raam, watching Dregoth, Nanda, and Sielba specifically.
Sielba - Returned to life when her mind, body, and soul were combined. Has only recently been discovered to be rebuilding Yaramuke.
Andopinis - Stuck in the Black, working with a shadow wizard and his shadow templars. Attempting to find a way to maintain his connection to the elemental planes so he can grant spells again. Has a keen interest in what’s happening in his city, but no desire (or ability) to return to it.
Oronis - Still sitting at home, afraid to fully transform and lose the rest of his humanity, spying on everyone and not being terribly effective anywhere.
Lalali-Puy - Pushing the Forest Goddess vibe, actively trying to enslave spirits from more than just the forest and trying to push it’s boundaries even further.
Daskinor - Still mad, doing his own thing.
Kalid-Ma - Recently returned to life and to the plane after the orbs were brought together. Has a small population and is trying to understand the changes that occurred. Is very interested in Baltic and what’s going on there.
Other Champions:
Sacha - Ressurected at the Pristine Tower when Rikus killed him. Has a full body now and has become a stage 1 become a dragon, trying to find out what happened to Rajaat.
Wyan - Believed dead but was recently uncovered by Sacha
Egendo - Freed from the Cyst, getting his bearing still.
Pennarin - Still dead
I’ve got a few of my own Champions active in the tablelands such as Sielba’s sister Cielbia, Irikos, Arenek and a few more out beyond it. My current party recently found the homeland of the Yaun-ti and has so far discovered a champion nearly defeated her race of ancient serpentine beings before realizing she was cut off from the tablelands and infused the last of that race with her human army to create the Yaun-ti so she could exist forever and keep her sanity.
