In two DnD videos, it's been stated that the Dead Three (Bane, Myrkul, Bhaal) have been reduced to mortal demigods in the mortal realms as a penalty for wanting to continue directly interacting with the mortal realms.

By itself, this doesn't really fit with how the Dead Three have been presented - they're neither stupid enough, reckless enough, naive enough, nor brave enough to give up their godly power to such a large degree, at least not AFTER what they learned from the Time of Troubles.

In addition, Mystra's physical appearance in the novel Spellstorm would suggest that avatars can still be created on Toril without giving up the greater part of the main body's divine strength.

It therefore makes more sense if the mortal presences of the Dead Three are not their main bodies, but rather mortal avatars projected from their divine realms.

AO'S DECREE

A possible explanation that brings things together amicably is that Ao has decreed that all gods of Realmspace can only project a single, limited power investment avatar INTO Realmspace, with the power of a demigod but most definitely killable by mortals. They can still make avatars OUTSIDE of Realmspace normally, but within the crystal sphere there is now a restriction.

How does this sound?
