Located in the basement of the mansion, Grimstone's burrow where he rests and hides and guards his treasure. The entrance to the horde is protected by wards to turn away any eyes he does not trust. The magic is constant and no scrying magics can see into the place. After you break through the wards you see a beautifully dug out tunnel that splits, one leads directly up to the surface where he can escape if needed the surface is disguised behind brush and trees. The other tunnel leads to his chambers where there are high stacks of gold and treasures reside. Grimstone will rest here as he protects his horde from any thieves or intruders. Enter if you dare and do not touch anything.
