The Divinity games are about a strong single-player experience. Multi-player support would invariably take resources away which could have been used to make the best possible single-player experience.
I also do not like the idea of ghost form to revive. That kind of thing is either a pain in the butt or a slap on the wrist. A pain would be a pain, and a slap on the wrist makes that mechanic pointless.
I don't know what Zixzax is talking about. The teleporter stones first appeared in Divine Divinity. One was in a sealed room inside skeleton filled catacombs, the other was in an elf's closet. And when Zixzax first appeared, he didn't indicate that the stones were his, he borrowed them from the Divine, then RETURNED them to the Divine later.
What will happen to the Dragon Slayers could be interesting. But with the return of the Divine with the help of a Dragon Knight, I think the order will be more likely to dissolve on its own.
The Dragon Knight might die some day, but that's probably not for a few hundred years. But I think it would be a good idea and interesting for the Dragon Knight to start restoring the order. Talana was not Maxos, but was able to change the slayer into a dragon knight initiate. Perhaps the Dragon Knight could do the same.
Lovis became corrupted, yes, but I don't see how that was any different from how a regular person becomes corrupted with power.
It would be nice to walk on Sentinel Island as the master of the tower.
