Green Lantern: Emerald Knights (2011)

As the home planet of the Green Lantern Corps faces a battle with an ancient enemy, Hal Jordan prepares new recruit Arisia for the coming conflict by relating stories of the first Green Lantern and several of Hal's comrades.

In Green Lantern: Emerald Knights, consciousness is carried by aliens — a plane of “interstellar law enforcement”. The story fights on E9/E10 of the E0–E14 reality ladder, compressing authority, duty, fear, sacrifice, control.
