Hircine is a daedric prince whose sphere is the hunt, great game, and the chase. He is typically portrayed with a great spear and either the head or skull of a deer. He is a sportsman and enjoys giving his prey a chance, however small. Hircine hosts a great hunt every era, pitting various prey of his choosing against one another and the nature of each hunt is known to vary from era to era.
Hircine is the guardian of were-creatures, having created various therianthropic diseases which transform mortals into beasts reflecting his sphere admirably, hunting at night and being hunted by day. Any mortal with the blood of a werewolf upon death is claimed by Hircine and sent to the Hunting Grounds. This has caused those who did not wish such an afterlife to go into hiding from the daedric prince.
His realm is called the Hunting Grounds and is covered in dense woodland, vast grasslands, plains and is filled with endless puzzling rooms and mazes inhabited by bears, wolves, were-creatures, and daedra which are all much larger than those in the mortal realm. Any mortals who enter are typically hunted down. Three artifacts are associated with Hircine:
Saviour's Hide: Resist magic and poison.
Spear of Bitter Mercy: Reflects magic and summons a storm atronach.
The daedric prince’s enemy is Ebonarm.
In Daggerfall he rewarded the player for hunting a rogue Wereboar.
In Battlespire the player had to pass through a small realm known as the Chimera of Desolation where Hircine's wild hunt was taking place and after defeating Hircine managed to escape the realm.
In Morrowind he rewarded the player after they killed a giant bull netch with the Fork of Horripilation. The player also fought and defeated him when he tried to enter the mortal plane in Solstheim.
In Oblivion he has the player kill a unicorn and bring it’s horn to him.
