Osirian WarScarab
From Tardis Wiki, the free Doctor Who reference
An Osirian WarScarab was an object of Osirian construction. It was made of an alloy light neutronium and osmidium and was essentially unbreakable. Its 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 WarScarab was located on Mars, where it served as a barrier in G'chun duss Ssethissi. (PROSE: GodEngine)
