Cadwell (Elsweyr Chapter)

Sir Cadwell of Codswallop is a cheerful and endearingly mad lost soul who resides in Coldharbour. He is the oldest of the Soul Shriven, and was already insane even before he left Tamriel. He is a pivotal character in the Main Quest as well as the Coldharbour invasion quests. Cadwell regards himself as a daring knight, and has spent so much time in Coldharbour that he has become a part of the realm, teleporting around at will and viewing Tamriel as only a pale reflection of his home. He has a pet bantam guar called Honor, though according to him, it is his noble steed.
