Walking Statues of Wideberth (/ˈwɔːkɪŋ ˈstætjuːz ɒv waɪd bɜːθ/)

Scattered throughout Wideberth are eight enormous statues that can defend the city in times of great peril. Because they are so destructive, the walking statues are used only to fend off armies and seemingly insurmountable foes.
Each statue has a name and a unique appearance, but in terms of statistics they are similar. The statue known as the Swordmaiden is too broken to be animated, and only the wielder of the Blackstaff can animate the other seven.
Landmarks. Over the years, Wideberth citizens have built structures around and on top of several of the statues, believing them to be little more than landmarks at this point. In their inanimate state, the statues pose little danger-but any structures attached to a walking statue are destroyed the first time it animates.
Constructed Nature. A walking statue doesn't require air, food, drink, or sleep.
These were seen starting in Session 21: The Yawning Portal Report...
