Feast of Fehmarn is celebrated by the Sommlending on the first day of spring. Among the festivities, children of seven years of age swear their fealty to the King of Sommerlund for the first time. Those that had already taken the oath would renew it at this time.
All the Kai Monks from all over Magnamund gathered together during the Feast of Fehmarn. They fasted and meditated on the eve of the Feast of Fehmarn. It was said that a Kai Lord would lose his disciplines if he missed this observance although no one truly believed this superstition. Also, the acolytes that had been in training for a year or more were given their new Kai names. This secret gathering allowed Darklord Zagarna to massacre the Kai.
