Brother Erelim led Volturno squad, 5th company for over a century, before falling to the vile Tyranids on Taumna IV.  He led his squad on a daring attack on a gargantuan Hierophant.  He was able to use his lightning claw to open up a joint in on the creatures massive legs, and plant a melta charge that was able to cripple the monster enough for the chapters Storm Ravens to bring it down.  He was almost killed in the explosion, and the noxious poisons and spores were able to compromise his battered body.  Brother Elim, the only surviving member of Volturno squad, was able to evacuate Erelim’s failing body.  The Calix priesthood quickly decided to entomb his body in one of the chapter’s precious Dreadnoughts.

Erelim Domitianus was reborn and now serves the chapter with the same daring he did in his prior life.  He favors a close combat load-out using the twin blood talons, that mirror the lightning claws he used as an assault marine, though he has been known to take a frag cannon and heavy flamer for boarding actions.
