I did search but couldn't see any.

Basic notes:
Second founding.
Fleetbound.
Imperial Fist geneseed with mutated (empathic?) Omophagea.
Planetary assault specialists.

Known special Psychic powers: The Hell

Their planetary assault heritage suggests a more aggressive abilities than the usual ImpFists. They are much more inclined to besiege than to sit behind defences.

Maybe basic Imperial Fist with a modified skill list?
ability mods: ?

Not sure about the mutated Omophagea. I thought giving them the "Reading" psy power effect on their lunch might be too powerful.

I've only put a cursury thought into them, but my thinking was as a side effect for eating their fallen foes, they gain proficiency in one xenos weapon of the race that they just ate. Or possibly a bonus on various checks made within the rest of the mission when dealing with the xenos race.

I'd imagine them to have a lot of dark secrets, with some fallen members too. After all they're walking a fine line with those heretical habits.
