Lair of the Traitor

 Lair of the Defiler is a lair located in Optoria in the West corner of the map near the ocean. It is a crypt found within a graveyard. The occupant is Gerves the Traitor. Access A clue to opening the gate in the form of a riddle is found in the Tomb of Knowledge: Four keys to open One East, One West, One South, One North ''To find them all is improbable To keep them all is impossible

There are four gravestones outside the lair that are selectable. Under each stone is a coffin full of rocks.

Opening the lair requires travelling to Okami's Vault of Artefacts where there are four keys which open the great gate that prevents people from entering.

When the riddle had reached Okami they decided to give one key to the High Elves, and hide the other three.

If the keys are all found, inside the lair are a number of undead soldiers which defend the lair. Inside the lair is Cornfeil the Traitor, Corzhail Furybane's ancestor. If he is killed it is said that a great treasure hidden in the lair may be found.
