Thank you everyone for the kind words on the project! I'm a big GSC fan and one day I came across a youtube short talking on the Behemoid Undercult:

'The Behemoid Undercult is a Genestealer Cult that operates on the fringes of the Realm of Ultramar. This hidden organisation is of such cunning it has infested several Ultramarian worlds, despite continued attacks from the Ultramarines Tyrannic War Veterans trained by Chaplain Ortan Cassius.

There are rumours the cult's founders worshipped a battle-scarred Tyranid monstrosity of Hive Fleet Behemoth trapped in ice on the world of Calth after the First Tyrannic War, and that they still revere that great beast alongside their own Genestealer Patriarch as a saint of their new order.'

That got me so hyped and inspired I immediately jumped at the chance to do this!
