Vieda

The divine spell known as Vieda performs much the same function as the subsequent Britannian spell, Peer, and can substitute for costly peer gems.

Spell Description
A navigational aid, invoking the spell affords the wayfaring cleric a bird's-eye view of the surroundings, be they a dungeon, settlement, or wilderness. Vieda does not identify proximal threats; it does, however, indicate various obstacles inside dungeons, such as doors and fountains.
