Airmark's Guide to Planar Vegetables: Gehennan Grafting Tree
If no other plant in this flora encourages the reader to stay far from it, let it be the Gehennan grafting tree that does. Resembling a dark-barked oak tree from a distance, only the smell of cloying rot serves as many travelers' warning against the danger this predatory mimic poses. By the time a better view can be had through the choking ash and smoke of the Gehennan sky, the danger is upon them.
Once battle is joined, this tree's common name becomes clear: under normal circumstances, grafting is a practice of joining two plants or parts of plants together so they may grow as one. The gehennan grafting tree, born from a plane infused with selfishness, perverts this tendency to its own ends by rending flesh from bone and grafting it to its own trunk and branches.
Typically content to lie in wait before snatching prey out of the air or off the volcanic slopes of Gehenna's mountains, grafting trees are indiscriminate in their attacks, snatching fiery elementals, yugoloths, and mortals alike in their ever-ongoing effort to grow their own bulk by including animal flesh in their form. Capable of tapping into internal reservoirs of toxic volcanic gases, these trees remain difficult to locate and attack in their self-generated smoke screens.
Grafting trees are both mobile and intelligent, and are thus capable of setting their ambush anyplace they choose and offering to work with others for short-term gain. They also seem to have some culture of their own, and will periodically meet to compare their newest acquisitions in a ghoulish spectacle not unlike a county fair in reverse.
