From my own perspective, I like the idea of someone gathering the orbs, the last one being within Grey Kalidnay itself, then using the Dark Powered body of Kalid-Ma to resurrect her while sidestepping the requirement of getting another SK involved. There’s a ton of work that would go into actually finding out it exists, then actually getting there. Once there you have to do with Thakok-An and the renegade templars who oppose her but I think if she can swing it to her being responsible for waking Kalid-Ma she’d do it.
Once awake Kalid-Ma would be sane, the body would morph into a 7th level dragon as it changes to meet the expectations of the mind that occupies it, and Kalid-Ma would start looking at getting citizens back to Kalidnay and reestablish her power (and deal with Thakok-An). Due to the comments below, I’d have her focus more on dealing with the current Trade Lords, the Shadow Templar Council, his old friend Andropinis in the Black, and al the changes that have occurred. I’d play up the friendship between the SMs, considering that Androponis undoubtedly knew what she was up to, didn’t say anything, and didn’t help kill her.
For Andropinis, I wouldn’t have him return. I’ve read a few places about his return 1000 years later or managing to find a way back early. For my own campaigns he’s still stuck in the Black and always will be. Rajaat cursed him with “eternal confinement” in the Cerlean Storm novel (pg 314) and was about to hit Nibenay with a 1,000 year torment when he lost the Lens (pg 315). He’s in the Black, contactable by spells, his remaining templars were trained by a shadow wizard to utilize energy from the Black and contact him. I’ve got plenty of fun with him trying to further his aims in Balic without actually being able to step foot outside the Black.
He’s trying to increase his Templar’s power, find a way to connect to the elemental planes to grant spells again, torment some elves, and get things back on track. I actually had a Shadow Wizard try to free him at one stage in the hopes of a great reward. He was able to find Andropinis in the Black, open a portal to him, only to find he had absolutely no interest in going back to Athas physically. The Curse was such that he can’t even conceive of a reason WHY he would want to. When the Shadow Wizard tried to force him by moving the portal, the portal went right “through” him as though he was intangible, so he physically couldn’t go back to Athas. He ended up being the one who trained the templars.
