The Sorcyst Blade is a magical longsword which teleported any creatures impaled upon it.
About
The Sorcyst Blade was actually the full name of the weapon, which contained two weapons --- a longsword, and a dagger. The two were attuned, and when a specific sigil was carved into the ground with the dagger, that would become the teleportation destination point for anyone stabbed with the larger of the weapons.
History
The Sorcyst Blade was stolen from the archives where it sat in the City of Galik by unnamed thieves sometime around 450 PR. When the blade was tracked down and brought back to the city by Golkont the Hawk Mage, the city rewarded Golkont by allowing him temporary ownership of the blade.
