The zone itself is named after a large mountain, the eastern side of which has fallen in upon itself, to form a likeness of a skull.
In Brokenskull Rock (S) is a troll village, complete with blacksmith and spiritmaster, for those characters appropriately aligned.
A shipwreck is haunted by zombie sailors and drowned ghouls in Brokenskull Rock (W). Each of the stationary undead in this area is a placeholder for Captain Rarehab.
In Brokenskull Rock (N) and (NW), nearby the various Taw Ew camps, spawns the curiously named panther, Panthor.
The Tae Ew camps themselves are thriving with the fearsome lizard man, and the northern regions of this zone are particularly dangerous for new adventuerers traveling solo.
