Vryo is the firstborn son of the Queen, Evros. His father, Quartz, was a loner who left the pack before he and his sister were even born, so he has a lot of resentment towards him. Vryo decided to form a second hunting party to assist his stepfather, Kokkinos, in supporting the pack. When Vryo's mate, Mavros, suddenly ran away, he became slightly bitter towards her brother, Dyo, but grew much closer to his adopted son, Permafrost. He retired as a sangui to make room for the next generation of hunters.
