Anchient GC Avanger class- used over Zephyr for orbital/system defence as its warp drive burned out ages ago. Taken by storm using assulat marines followed by regular marines.

As a part of the deal to rise Vinis-12 in Mechanicus Rank (and gain the host more production ships) A new Warp drive was gotten and Zephyr prime joins the other GC in the 1st Crusier division.
