Sokol Lazarus, Cybernetic Guard Edit
Lazarus is a member of Kryzak's personal bodyguard. He appears to have undergone Emotional Repressive Surgery, rendering him incapable of emotion and thus immune to fear. Lazarus has been injured many times while protecting his master, and much of his body has been replaced with bionics.
Additional: Recent reports suggest that Lazarus has been fitted with either recovered Tau artefacts, or with technology based on knowledge gleaned from examination of such artefacts. Suggest detaining Lazarus to ascertain the origin of the implants.
