Expanding forgotten lore: Centius Prime Episode 2. Epic scale grimdark future

Cenitus Prime was attacked by Ork Boss Gigagob but the lore feels incomplete. In this series we will try and expand upon it and have fun in the process.
The Iron wolves company makes planet fall but find themselves jumped upon by an ork strike force. The marines are able to get 6 tanks out the door immediately to hold back the orks while the rest of the vehicles are made battle ready.
