Shocked everyone, basically. Aside from PC, she was the main heroine of the game. As of right now, they wanna wait a bit for players to miss her (remember how furiously did you tear Adria limb from limb... this was personal).

Currently, I see six ways for her to be brought back:

- A 'ghost' NPC, a role similar to Cain in D1-D2 (i.e. accompanying you in every act), in a state much like that of Zoltun's.

- A complete resurrection, with the aid of Zoltun (who owes her one) or someone else.

- A partial resurrection, in a demon or human host body through the last sliver of the Black Soulstone.

- As mentioned above by Hawki, grant her peace in the afterlife (which will be especially surprising if it leads to the previous variant, as she is 75% demon, so maybe she can return from the Black Abyss).

- Return as a follower, as one follower is currently missing in the game (bard-like class, with bow and dual-wield, item identifier, fits her perfectly).

- Not returned at all, go love someone else.
