Pilgrimage of the Evening Star

This is a journey of an "alien" observer on a fantasy continent; an abyssal journey into the hinterland of civilization; and a journey of self-discovery and growth. Female protagonist, partial to group portrait POV, traditional Western fantasy, three elements: no system, no time travel, no daylight. It can probably be regarded as a road movie about exploring and committing suicide for the first time as an outsider enters human society (?)
