AO is told from Abe's point of view. Maybe Abe learned to chant in Monsaic Lines and only escaped from Rupture Farms by himself but wanted to tell us how he was all heroic and shit and had awesome mind powers as a slave and rescued some mudokons before escaping.

Or not.

Edit: I imagine the chant suppressors are there to stop any native mudokon from coming to RF and possessing everyone.
