Branchdusk's Links
He's often been mistaken as Ghosttree's biological son--he himself had once thought the same. Their relationship is a relaxed one. Branchdusk understands that Ghosttree isn't like other parents and cares about him anyways.
He isn't able to keep up with Branchdusk's sociable and fast-paced nature, so he lets him run wild for the most part.
He's seen the spirit of his grandfather for most of his life. He enjoys talking to Brook and feels a kinship with him, and not just because they're family.
He's very proud of Branchdusk. He followed Branchdusk around and spoke with him his whole life, watching him grow old.
