Halsin is a patient, passionate, knowledgeable, and wise druid. His true passion is healing, and he is devoted to his people in the Emerald Grove, where he serves as Master—a role he did not seek for himself. He is confident in his abilities and in those he trusts. When introducing himself, he places a fist over his heart in an earnest gesture, preferring to be called simply 'Halsin' rather than by his title.
