Portal Rock

The portal rock is the gateway between Morthain and the Realm of Exile. It is formed from the magical rock morth, and serves as the only key to teleport between these two places. It is capable of teleporting to other places as well.

Another feature the portal rock has is the path guide, a light that shoots from the stone and guides the holder to the teleportation mark located in the Realm of Exile.

Immunity to Magic
Another secret feature, created and known at first only by Masoro, is its immunity to magic. Whoever holds the rock is impervious to any other magical force. This power, combined with the skill and speed one gains when wielding the Sword of Morthain, makes for an unstoppable force. This combination was never meant to be given to one individual alone, but more as a system of checks and balances between two indiviuals. Masoro eventually became corrupted by this thought which began his spiral into wickedness and thirst for power. Soroth is the only one who ever obtained both, which ultimately led to his own demise.
