Currently writing his backstory and setting up important stuff.
He hungers for gold, gems, but mostly feathers.
The ones you see aren't his, but angels' instead... which were used as part of his Royal Mantle (Decoration).
The big ones on his neck and shoulders were taken from Dominions and Principalities, while the ones underneath were taken from Zealots and Heralds.
He's rather envious of the King of Violence, however, whose crown is adorned with Seraphim feather instead... and it's no mere Seraphim, but the Heavenly Council's Grandmaster Lother: Grandmaster Lother (who I'm redesigning a bit to fit the new lore)
