   Long ago, a man named Durham walked the earth.  He was a traveller, an
explorer - it is said that there was no place in the realm that he had not
seen or visited.  A terrible fate befell him, and he was killed by a powerful
evil cleric.  Before his spirit could pass on, the cleric cast a powerful
curse, causing the spirit of Durham to forever walk the lands he knew so well.

The spirit of Durham may be summoned with this spell to provide the location
of another person.  Once the spell is cast, the spirit will appear, and wait
for a token (typically one gold coin will suffice).  If Durham's spirit is
satisfied with the gift, it will search the realm and tell you approximately
where that person is.

The spell only binds the spirit for a short period of time, and if the spirit
does not receive its token, it will leave.
