Hierarchy of Laguna
"A Dominion in the Second Sphere of angels. The name Gravitas means stern and severe, so this angel is often depicted as steep, uninhabited mountains forever frozen in ice. His extreme cold has been unpenetrated for eons, and it shows no change through the passage of time. Gravitas awaits silently for an opponent willing to sacrifice everything to face him."
