The ancient and mythical blade Tuvryn is the most powerful sword known to exist in history and even mythology. It has rarely been seen and in fact has appeared only three times so far in the world’s history. The blade is bonded to a wielder, but can be broken and exchanged if the wielder so desires. The blade does not have a sheath. Instead, the blade disappears into the mist when it is dropped. To summon, the wielder sends a mental command and the sword simply appears in his hand, blade slick with dew. The sword is known only to have come in times of great need, often to fight large forces of evil from the Planes.
The blade is said to have been forged by the Gods themselves.
Apart from this passage, not much else is known about this blade.
