Gols

Rules Maps Journal Ship Laboratory Equipment Codex
These creatures were first encountered on Doria, fighting alongside Vailwer that had been turned into crystal husks. There are no records of these creatures in the databases of the Citadel or the Batarian Hegemony, at least not in any of the public databases. No one seems to know what they are, or who they came from. Analysis of their communications and equipment seems to indicate that they call themselves “Gols”, but even that is uncertain.
They were armed with energy weapons that fired small pulses of highly energetic particles. These pulses were very good at penetrating standard shields. Physically they didn’t seem very strong, though pain didn’t slow them down much. Examining the bodies was difficult, but they appear to have some organic-synthetic integration, much like the Citadel Keepers.
