Auguste is a Saradominist monk living on Entrana. He is tired of living on the island but his desire for a more exciting life has finally convinced him to seek something more. He can be found on the western coast of the southern half of the island.
Auguste is the inventor of the first hot-air balloon, and convinces players to help him fly around Gielinor in the quest Enlightened Journey. Once the quest is completed, players have the ability - with the required Firemaking levels and appropriate type of logs - to use the Balloon transport system to fly to various towns and places.
If players have a bomber cap and gnome goggles with them, Auguste will sew them together into a cap and goggles free of charge.
- His name and occupation are a reference to Auguste Piccard, who was a Swiss balloonist.
- His appearance and character are also a reference to Jean-Luc Picard, a Star Trek character who, strangely, was based on Auguste Piccard. On his collar Auguste has only three gold studs, unlike Jean-Luc Picard, who has four gold studs marking his captain rank.
- He was a "test dummy" for updated chatbox faces before a graphical update.
