I believe there were 3 quests, the card she gives you is in your inventory, and the back
of the card has the clue on where to go. I remember 1 was in Old town, as soon as you
enter the correct region, your dog will immediatley go for the dig spot, so all you have
to do is guess the correct region

the oldest part of the city - bowerstone old town
dark cathedral over looking the ocean - rookridge
where the dead dwell - bowerstone cemetary
life, fertility and rebirth - oak field
long been home to wanserers and travelers - Gypsey camp
dense forests in the shadow of a tower - brightwood tower
winding path by the ocean - bandit coast
sea licked sand looked upon by mountain etched in combat - westcliff
some where in the region of a previous artifact were found, some where in a cave ....
