Tentacle Root Den

An underground series of tunnels with quite a few large open areas, there are tree roots dangling down from the ceiling like tentacles, if one were to ever let their guard down around the tree root tentacles, it would grab onto their wrists with a firm grip completely immobilizing them and it'd be the end of a journey.

The den is also home to quite a few monsters that have learned to wait (drink tea) and take advantage of the tree root tentacles' immobilizing abilities.
