The Collector is an old fisherman who lives in The Holm Oak Thicket. He is a native of the island, one of the few that remained after the establishment of the community. As Daphne converses with him, he reveals his backstory and some additional information regarding the community and the mysterious Trials.
The old man is a self-proclaimed "collector" of various items. He is willing to assist Daphne if she first does a favor for him. When his initial suggestion that this favor be sexual is rebuffed by Daphne, he relents and offers instead a quest to locate his diary. If Daphne helps him locate his diary, he is willing to trade certain items.
