This wiki contains spoilers for all stories of Critical Role. This includes the story for unaired episodes of The Legend of Vox Machina, as it's based on the first campaign of Critical Role from 2015-2017.
Lying in the the center of the Open Quay, Tidepeak is a singular 450 feet tall massive tower that looms over the entire district. It has a diameter of 90 feet and has no doors or windows. It has a number of small balconies dotted around the tower and it comes to a slight roofed peak that is a sharpened point. It is made of dark- and light-flecked emerald stone. It sticks out, and there are no buildings up against it.
The tower seems to have some sort of permanent illusion cast over it which makes it appear smaller at a distance, and grows to it's full height when approached. This enchantment allows the tower to seem unobtrusive and inconspicuous on the Nicodranas skyline.
Tidepeak houses its own teleportation circle, with its use reserved "for the select friends" Yussa Errenis keeps.
