When players light the beacon near her, players may pass Squire Fyre five logs (the same type that were used to light the beacon) for her to tend the lit beacon with, allowing the beacon to stay lit longer.
Squire Fyre says she originally intended to be an 'Arcanist', but due to an administrative error, she was put forward as an 'Arsonist'. This is a reference to the popular Funorb game Arcanists. Ironically, she is more than likely an arsonist.
Blaze Sharpeye says that he quite likes Squire Fyre's style of Firemaking. He may well have a romantic interest in her.
