A Guiding Spell referred to a short incantation which conjured an emissary from beyond the Earthly plane to light the way for travelers who had become lost or disorientated. This emissary took the shape of a green floating light which would await instructions on where to lead the caster.
Aradia, Goddess of the lost. The path is murky, the woods are dense, darkness prevades. I beseech thee... bring the light!
