[WH40K] Let's make a new Chaos God!

While the births of Khorne, Tzeentch and Nurgle are a bit nebulous, we know that Slaanesh was born from a centuries-long, violent mega orgy that included almost the entire Eldar race.

What would it take to make another one? What kind of Chaos God could we create? Are there emotional aspects not yet covered by the Big 4?

There is another one, shunned by his/her brothers. 

Malal, the 5th Chaos God, god of chaos itself. It does its destruction purly for destruction.

No honor or glory like Khrone.

No "comforting the universe" like Nurgle.

No pleasure like Slaanesh.

And no change like Tzeentch.
