Summoned from a mysterious land far to the east, Maximus is a literal Dog of Steel.  Or at least a steely-looking substance, we're not exactly sure.  Every time we ask him, he starts going on about being forged from the rarest of alloys in the ancient foundries of the Old Gods, who walked the Earth long before mortal man... blah, blah, blah.  He just goes on like that forever.  I really do try to keep up, but how many times can you hear "Titan-forged War Dog" before you just shut off.   

Anyway, he comes to show his support for the Dogs of Steel.
