Journal entry

 * ''Upon a notice board in Toussaint, Geralt found a call to all who wished to submit to a Test of Virtue. The notice's mysterious author summoned any who dared to an isle upon Lac Célavy, where they would have a chance to prove their worthiness of character. He who successfully completed the test would receive a reward. Though Geralt had never thought of himself as particularly virtuous, he found the summons intriguing and decided to go to the appointed spot to learn what the trials entailed.
