I know that the Darklord of the non-Vecna Domain was Kas the Destroyer, but who was he? What tie did he have to Vecna? What made Tovag and Cavitus seperate if they were so tied, but still attached them as a cluster?

To expand on what Stygian Inquirer said...
Kas and Vecna were both of Oerth, the GREYHAWK campaign setting. After Vecna rose to power, he enlisted the aid of a powerful warrior named Kas to enforce his judgments and commands as his servant. If you were an Oeridian and you went against what Vecna commanded, Kas would show up with his enchanted sword and there'd be almost nothing left of you to bury (hence the nickname, "The Destroyer").
Unfortunately for Vecna, the Sword of Kas was heavily enchanted, evilly intelligent, and apparently upset at Vecna for not giving it a better name.

It whispered to Kas, tempting him to turn against Vecna--which eventually he did.
Unfortunately for Kas, the Sword couldn't actually HARM Vecna--I think it lost all its powers when in proximity to its creator. Nonetheless, Kas was a majorly-powerful bad guy, so they battled and apparently destroyed each other, and Oerth breathed a great big sigh of relief.
Except that Vecna achieved demi-divinity, unleashed a bunch of mad plans to ascend to full godhood, and was ensnared by the Mists in the process. As part of Vecna's torment (other than his imprisonment), the Dark Powers brought Kas--now a powerful vampire--into the Mists with him and gave them both neighboring domains: Cavitius for Vecna and Tovag for Kas.
IIRC, they were a cluster because Kas and Vecna still hated each other and it was part of both their curses to be in such close proximity to each other and still be unable to actually kill the other (and be unable to close the part of the border their lands shared). What differentiated them were their environments--Cavitius was more-or-less a big chunk of the Quasiplane of Ash where everyone outside the citadel pretty much died quickly, and Tovag was a more-or-less inhabitable place where everyone aged at double the normal rate so Kas would have a ready supply of cannon-fodder to shove at Vecna.
