Lore

Warmaster Seerus is the evil master of munitions within the gremlin's all-powerful Crimson Order. Thought to be the true mastermind behind the Roarmulus Twins and countless other gremlin weapons, he is the Crimson Order’s creator and supplier for their diabolical engines of war.

Recon Knights under the command of Liutenant Feron recently discovered Seerus’s ‘Grand Arsenal,’ his development center and storage facility for all his weaponry. Now, Feron himself is leading several squads of knights directly into the Grand Arsenal, with the intention of weeding out Seerus and destroying his war machines.

Met with heavy resistance, Feron’s squads require reinforcements and Spiral HQ sends several knights to aid them in their assault.
