This is Rhombus the baedyr (BAY-deer). Baedyr are magical creatures which reside in a magical world where comatose people's contentiouses reside. the baedyr protect these contientiouses, because they can very much die in the coma world. if they die in the coma world, they die in real life so protecting them is important.
"
Rhombus in particular is a sass ass who is put in charge of protecting a little anthro dog kid just referred to as "kid". i think it would make for a cool graphic novel or something
