Arachnis Brood-Keeper

Arachnis Brood-Keepers were organisms of unknown origins (although it is possible that Arachnis is the name of their home planet, similarly to Zz'gashi Dune Runners). Like so many other specimens, they were assimilated into the Zerg Swarm, effectively eradicating the species. All that seems to remain of their species is the Zerg strain created from their DNA - the Queens.
