Messenger World A
Appearance

Messenger World A, or Messenger Island A, is the part of the Land of Ruins that is accessible:
- in The Talos Principle, by using the axe (from the Land of Faith) to break the wooden barricade in front of the portal to this world.
- in TTP: Reawakened, by collecting Messenger Tokens and unlocking the door in Building A.
Puzzles
There are five sigil puzzles, four of which unlock puzzle elements and the fifth of which releases a messenger.
Stars
There is a star hidden in this level in TTP: Reawakened. However, in the original game, this world geometry (and the corresponding star) was in Messenger World C.
