Canaam, Chanaam, Chanaan
Canaan and his brother Simeon were shown to lack faith when they were not served, like the other followers, by the Grail. Jealous, he murdered all of his brothers except for Simeon in the middle of the night. In punishment, the Christians decided to bury him alive. Canaan repented at the last minute, and was granted his request to have his dead brothers buried around him.
Later, Canaan’s tomb burst into flames, and he suffered inside it for hundreds of years, until he was delivered by Lancelot.
