Avarius is a clone of Sirius Fulmaren, created on Day 4. The clone was created during an emergency procedure while the real Sirius was fixing the magical core of his laboratory. Sirius created the clone as an attempt to carry out his will while he repaired his lab. Avarius only discovered his true idenity on Day 7. While on a recon mission to find the agents of King Dromand in Hyrule Castle, Bernard Kotaro informed the agents that Avarius was a living bomb. He was intended to explode in order to remove any threat these agents had at stopping the real Sirius' plans to take control of the timeshift stone vault. Taden Horwendil killed Avarius in an attempt to stop the explosion, but only started a countdown. Avarius' body was vaporized when he blew up in he dungeons.
