This is funny because sauron wasn't around when the war of wrath happened. He feared morgoth's wrath because he let luthien and beren take over The tower of the werewolves, formerly known as minas tirith. (Not the white one in gondor)
Headcanon time War of Wrath coming to the end, Olorin faces Sauron on a threshold of Angband. Art by Phobs. Absolutely epic - I've always been intrigued by the Maiar, and I've always wondered how they related to one another during times of war.
