The Reason Zenos.

[Evraeh]

I wish we get sometime a back story of Zenos in the level of Emet, to anwer why he is strong, or his personality.
Emet without any of ShB would be just bad as zenos, but now it's a whole villain that we love.

I wish to know it as well. I didn't like him in SB but since ShB, I want to know more of him. I feel him to be a great villain if we could know more of him, if he could be more related to the hero like Emet-Selch did.
