The PC is instantly aware of any beings within 20’ who possess the same alignment as himself. For example, a paladin knows when a lawful good Aasimar has just stepped behind him but does not learn the alignment of the lawful neutral good Deva crossing in front of him unless he employs some other means of divination.

Regardless of whether the PC is a spellcaster, he understands how the unique nature of his home plane affects magic. This includes which schools of magic are affected, how it is affected, and why ("You’re on Mechanus berk – wild magic is useless here and against the law."). This ability does not provide other magical insight, such as spell keys.

Upon sight, the PC instantly recognizes any beings who originate from his home planet as a fellow native. Only true natives of the PC’s plane can be discerned. This ability does not grant the ability to recognize those who migrated to the PC’s home plane from another plane. The PC does not gain any other information about the beings he encounters.
