Poseidon's Lake is the developer name given to the arena of the 12th colossus. The name 'Poseidon' refers to the developer name of the colossus.
Description[]
The beautiful lake that stretches behind the waterfall is the stage for the battle. The lake is dotted with five platforms, three of which have roofs. The roofed platforms have many obstacles such as pillars and pedestals, which are useful for avoiding the attacks of the colossus.
Location[]
The arena is located on the east on of the Forbidden Lands, near Misty Falls, at quadrant G2.
Trivia[]
- In the Preview version of the game, a short version of the theme Commandment plays when first finding the arena.
- Misty Falls was called Turtle Falls in the Preview version, possibly being a nod to the 12th colossus' concept name: Turtle II.
- In the Preview and earlier versions, the center of the lake had a giant indentation which would make a significant part of the colossus' body be submerged by water if it walked on it, giving the player another way to climb it.
- In the E3 Demo version, there are no vines on the pathway for leaving the arena; meaning Wander is stuck there until he beats the colossus.
- This, coupled with the 12th Colossus' body staying submerged after it is beaten in this version, suggest that the Reminiscence Mode wasn't in the plans at all until very late in development.
- In the E3 Demo, the cutscene for this arena can only be accessed with the debug menu or by modifying the code. The theme named "Sanctuary" (also known by its file name "cave") plays.
