As part of the Cult of Cinders chapter for the Age of Ashes, one of the goals of the group is to destroy or disable a series of Dragon Idols constructed by the Charu-ka and Boggards. This towers are magical, and have caused the Ekujae Elves to go blind whenever they approach (along with a few other surprises).
Unfortunately, such a central terrain piece is not readily available for printing or purchase, so I had to get a bit creative and design one myself. Admittedly I am mixing cultures quite a bit, since I used an existing model of a Tiki (which is Polynesian rather than Amazon rainforest), but I think it should give at least the right impression.
The model was a simple construction in Tinkercad: duplicate the Tiki four times, and rotate around a central core. Once printed (and hopefully painted), it will serve as the center piece for each encounter during the chapter, since there are several such towers the group needs to deal with.
