In that case, how about this ability (it's the one you posted with a new name)?
Sense Alignment (Su): As a standard action, a narra can sense the alignment of a single creature or object it is touching (chaos, evil, good, or law) as well as the power of this aura (faint, moderate, strong, or overwhelming - see the detect evil spell for details). This ability requires a successful touch attack if the target is being uncooperative. The narra does not risk being stunned if it senses an overwhelming aura with an alignment opposite to its own. This ability can be fooled by any spell, spell-like ability, or supernatural ability that masks a creature's alignment.
