Stalkers may drop in for a visit as part of a maestro event.
The message "A decaying stalker leaps in from above!" (with adjective randomly selected from the standard set of zombie adjectives) is displayed when the stalker appears.
It will attack the target of the event after appearing.
The maestro event cannot begin in the north part of Dunglen, but can still finish if the target of the event moves from the south part of the city to the north.
The decaying stalker is a normal NPC.
The decaying stalker is rated as a quite unskilled zombie.
