The final ingredient

The Great Gate
The planes of Oblivion within the gate is a single level map with a number of scamps, both fire wielding and melee attacking. The Great Sigil Stone is in the most North-western corner of the map. Once the Stone is activated, the Champion will take it. It is then merely a matter of returning to the Oblivion gate at the level's entrance. Once the gate is activated, the quest will end.
