The only known major event to have occurred in the Watchtower is seen during the Forgiveness of a Chaos Dwarf quest. During the quest, a Black Guard patrol led by Colonel Grenda was attacked by a group of chaos dwarves in the mines while on a routine police mission. Six members of the Black Guard were killed before an adventurer and Commander Veldaban arrived. Working together, the two killed the last surviving chaos dwarf hand cannoneer, who was hiding on the top floor of the tower. The event ultimately caused the two to discover The Red Axe's base in a hidden part of the south-west mines, and the beginning of open hostilities between the Red Axe and Keldagrim.
