Cragmaw Castle

Built on the banks of the Neverwinter River towards the eastern edge of the Neverwinter Wood, Cragmaw Castle is not a goblin construction, nor is that the structure's original name. Raised by a talented wizard-noble during the Age of Heroes, the stronghold consists of seven overlapping towers; however, its upper levels have long since collapsed to heaps of crumbling masonry. Only the ground floor is still solid enough to be habitable.
The centuries have not been kind to Cragmaw Castle. The goblins have shored up the weakest areas beneath its falling towers with crude timbers, but it is only a matter of time before the structure collapses completely.
