Osirian WarScarab

An Osirian WarScarab was an object of Osirian construction made of an alloy light neutronium and osmidium, It was essentially unbreakable. The hull was opaque to subspace fields, due to the Osirians' unique FTL drives. This was atypical of Osirian efficiency as they built their shielding into the molecular structure of their starships.

The hull of one such WarScarab was located on Mars where it served as a barrier in G'chun duss Ssethissi. (NA: GodEngine)
