Kerrigan the Arcanist

Kerrigan was a former Open Lord of Waterdeep, but he's the only Open Lord who doesn't have a statue in the Heroes' Garden. He killed the other Lords on the Council to come to power, then abused that power a bunch. His actions led to a huge magic battle in the South Ward, and to this day you can see the architectural differences from the damage. He's the reason magic is so tightly regulated in Waterdeep.

This is the tale as related to Smoke on the Water by Nef Artemel, so it may not be entirely accurate.
