Toredig

Toredig was a prominent Elf of Caerland, who suffered a tragic injury that left him paralyzed from the waist down.
Before this accident, Toredig was an excellent hunter, an elegant dancer, and a powerful druid. He was friends with the ancient elves Aderyn and Llyn'Hedfan, and an inspiration to his clan.
After the injury, Toredig was no longer able to even hunt or gather food for himself, and so was shunned by elven culture. The human druids of Liathae took pity on him, and provided him with food and shelter.
Decades of remaining in Liathae, surviving off the pity of humans, unable to travel, unable to do any of the things that are part of elven nature, Toredig became more and more depressed.
In 20.88, Llyn'Hedfan visited Toredig and conspired with him to release the Green Man, Un'Coeden. Toredig sent away Cerridwyn McDughal, and manipulated Aidan Branwen and Morgan Asalaine into releasing the entity. They later confronted Toredig, and Morgan killed him.
