How do you become a werewolf on Morrowind GOTY eddition without completing the main quest

You could fight werewolves in the wilderness of northern Solstheim. Like with their vampire counterparts, you have a chance of catching a disease while fighting a werewolf. This disease is called Sanies Lupinus, which if left untreated for a total of 72 hours will turn you in to a werewolf. The werewolf transformation takes place at 21:00 hours (9 P.M.) game time, and lasts until 6:00 hours (6 A.M.) game time.

Alternatively, you could use the cheat code:

Player-> addspell "werewolf blood"

You could also use the cheat code to grant yourself an enchanted ring that will allow you to become a werewolf whenever you wear it. The code for this is:

Player-> additem "BM_ring_hircine"

To use cheat codes, press the grave accent key on your keyboard and input them in the window that opens.
