Blaze Sharpeye is a Beacon Keeper in the All Fired Up quest and the All Fired Up minigame. King Roald III had tasked Blaze with the testing of the beacon system, and the subsequent management of the beacon network.
He is a witness of the suspect in Missing, Presumed Death.
When players light the beacon near him, players may pass Blaze five logs (the same type that were used to light the beacon) for him to tend the lit beacon with, allowing the beacon to stay lit longer.
As with some (or all) of the beacon keepers, Blaze has an impulse to deliberately start fires. This behaviour is called pyromania. He becomes quite crazed when he is talking about lighting fire, and this is shown then his animation changes to a wide-eyed expression and he usually screams something about fire, his chathead takes on a unique, deranged appearance.
