Accolan is an Aldean artist who becomes guardian to the abducted Enterprise-D child Harry Bernard and teaches him to carve wood with an Aldean sculpting tool.
Accolan appears in When the Bough Breaks. He is one of the Aldeans chosen to raise a child taken from the Enterprise-D, in the hope of rebuilding a people who can no longer have children of their own.
Harry Bernard, a boy who has been arguing with his father about having to study calculus, is assigned to Accolan's household because of his artistic leanings. Accolan hands him a tool that shapes wood according to the image in the user's mind, and Harry produces a dolphin on his first attempt.
Accolan is shown as kindly and sincere, like most of the Aldeans, which makes the abduction harder to condemn outright. When the truth about Aldea's damaged ozone layer emerges, he gives Harry back to his family.
