Like the night life, wearing electric-blue heresy armour, daubed with coruscating arcs of lightning, skinning your foes and leaving their gore-drenched remains around you, terrorizing people and denying the dark gods your tattered legion? Walk with the Night Lords!
Well seeing as I can't be a Tyranid (they just to badass), I'll just have to content myself with Black Legion. Fingers crossed for Death Guard in the future. Priase Nurgle!
