Here's my take! In my D&D world I'm calling it Viraat-Gular, the Lord of False Figs. Said to be the first tree planted by the first Human settlers of Hridaya, the man who planted it was buried beneath it and in consuming him the tree grew hungry for flesh. With time it has grown large and through corruption has gained a malicious intelligence. It now lures travellers with kala jaadu incantations learnt from the whispers of The Corruption for its carnivorous consumption. It employs illusions of the glorious tree it once was, attracting them with the smell of the figs it once grew and planting the idea in the minds of its prey that eating these fictitious figs will ward off evil. He's living in the Hollowed Weald, where all the trees are dead and mummified so I've painted in in grey with glowing magenta as the magical influence; still learning how to do OSL effectively but I think it turned out okay.
