We need more lore/backstory

With the new update we are getting another new Hero for co-op

He has a little blurb introducing him on the Stormgate website:

Kastiel, the Orphan of Wintros.

As the ruthless and amoral warrior-Regent of Arkhos, there is no hope in escaping his Nethersword.
Devoted to the pursuit of victory at any cost, Kastiel abandoned his people's traditional reverence of Animus.
He now drives the Sovereignty of Arkhos towards a secret, heretical objective–the collection and weaponization of Animus in order to destroy all his enemies.
Be it through his will, or at the end of his lethal blade, the culling has begun. 

However alot of these words mean nothing to me.

As far as I am aware we have almost no lore for the Celestials yet and barely anything for the Infernals either.

It would really help to build a connection to the game, to make the Heroes more interesting and to flesh out the game world if we could start to get some of this lore and backstory that it seems has been written.

I've seen many complaints since the start of EA that the game feels sterile, and that characters are boring and that seems largely to be born out of the fact we know nothing about any of them.
