Canonical Conundrum

Canonical Conundrum is an achievement in Halo: The Master Chief Collection. It is awarded by finding all Data pads in Halo: Reach.

Trivia
The name of the achievement may be a reference to the fact that content of the Data pads would seem to conflict with the established lore of the Halo universe. For example, the The Assembly featured in the pads appears to be made up of Smart AI's and exist for centuries, despite the firmly established seven-year maximum lifespan of humanity's smart AI's.
