On an island of stone Yrgrim built an arena. He proclaimed to his brethren that he sought a successor strong in will and body, and pure in heart. They would have to pass his trials in order to claim his weapons.
Many of berserkers and dragonriders answered Yrgrim's challenge, but all met with failure and death. Yrgrim held his trials for years until the challengers stopped coming.
Yrgrim then withdrew into a shrine of his own making. He crafted a door that would judge anyone before it as the first test of their spirit and body. If they had the strength to bear its gaze, they would be allowed in.
Disappointed but not disheartened, Yrgrim built a shrine to Tyr and entombed himself in it with his weapons, waiting for a time when a true champion will come.
The door wards would burn those that tried to open it with cleansing flame. Only those strong of will and pure of heart would be able to hold back the flames.
For the one that does, Yrgrim waits inside.
