Dapper is a hat-turned triangulum, and an owner of the Admin Journal.
Dapper was just a very dapper hat, until he discovered one of the Triangulum Journals in his tea pot. The journal had no number, but it had the amazing ability of keeping track of the other Journals, and which Triangulums held them. After a while, he became a Triangulum, though it is unknown how.
Dapper own the Admin Journal, a Journal capable of tracking other Journals, keeping tabs on which Triangulums own said Journals, and promoting/demoting the status of them. It also contains multiple spells and some information about the possible location of some Journals.
Dapper has a few powers: he can float and use basic Triangulum abilities. He also has the power to make a cup of tea that tastes just right.
