Havel the Rock was once a bishop and a close friend and battlefield compatriot of Lord Gwyn's. He served on the battlefield alongside Gwyn, leading a group of men in armor carved from solid rock. These warriors wore a ring to help them use their heavy armor effectively, and to show faith in their leader. Havel is found locked in a watchtower in the Undead Burg, long hollowed.
Havel wielded the Great Magic Barrier miracle in order to combat his sworn enemy, Seath the Scaleless. This miracle can be found on the path to Ash Lake. Its placement further cements Havel's role in the war against the dragons, which occurred in the vast expanse of archtrees below Lordran.
