Arqsheth (Cannon Archon) Creature 9

Believed to have once taken the shape of ballista-sized arbalests, arqsheths are living cannons who line the walls of Heaven to defend it against fiends. They often make themselves known to pure-hearted mortals who are either in the path of an imminent fiendish incursion or else struggling to vanquish a vile foe. They can be obsessively goal oriented and have been known to abandon a stalwart ally to pursue a fiend rather than delay the fight against their target.

Once an arqsheth destroys the object of their pursuit or determines that their wielder no longer needs their aid, they typically return to Heaven, but rare circumstances sometimes lead an arqsheth to remain in the Universe for an extended time. These arqsheths might find themselves embarking on long journeys with a loyal starship crew, standing guard over a seemingly abandoned planet, or taking up a post near a Drift beacon. They never reveal their motivation for remaining, and some suspect that arqsheths have a sort of sixth sense that warns of potential threats and leads them to take up such posts.
