Archmid-Tri

Archmid-Tri is a defence platform surrounding the forge world Metalica, in the Metalica System; it is not a planet. No coordinates are recorded.

Typhus and his Blightlord Terminators, together with Dark Mechanicum priests, performed a ritual on the platform that turned its guns, and the guns of connected platforms, upon Imperial forces. The action is dated to early M42, within the Sore phase of Metalica’s labour-rotation chronology, dated to cycle 990.
