Where do you find the Pegasus in oblivion

There is no Pegasus in Oblivion, the one that the previous answer was talking about is a unicorn, not Pegasus. It is very white and while attack if a weapon is drawn even if you basically own it. The location is called Harcane Grove. The unicorn is protected by three leveled enemies called 'Minotaurs of the Grove.' It is tied to Hiricine's Deadric Quest. If you partake in the quest, you have to kill the unicorn and bring its horn to Vajhira, which is the Deadric Prince. Hope this helped!
