Oppidan Island is one of the many islands Earth was separated into after The Abstraction, and the HUB world in Abstracted Planet. Despite being the first world in the game, many of the collectibles within it require items from future worlds to obtain.
Five of the Abstract Motes from this world are discovered in the opening cutscene, and used to activate Oppidan Island's core.
- Dust Roach: Giant cockroaches whose bodies are made out of dust, thanks to the Abstraction.
- Dust Commander: Dust mites that have grown to be even larger than the Dust Roaches which they now command.
- Obscuration: Otherwise known as Shadow Sprites, they are shadows which were granted independence during the Abstraction.
- Sprite Machine: Machines which produce hostile Obscurations. They can be rebuilt for ten metal to create friendly Obscurations instead.
