History
The sword Magebane was crafted as a sword of state for a mameluk ruler of Calimshan during the realm's Seventh Age, following the fall of the Shoon Imperium. It was used primarily to hunt down surviving wizards of the qysar's court.

It was later in the possession of a satrap of Manshaka. When they died after 1272 DR, the sword went missing.

Unknown to anyone, it later came into the possession of the mad wizard Keilier Twistbeard. In the Year of the Blue Flame, 1327 DR, Keilier placed it as the prize in the Blue Alley deathtrap dungeon in Waterdeep. It lay there, still unclaimed, by Year of the Wild Magic, 1372 DR, and only Keilier knew its whereabouts.
