Much of Shadaline is covered by jungle and rainforests which are far denser than those found on Norrath. It is a wild, untamed world that seems to push back against civilization. The dal found it to be inhospitable, but the kerrans were instinctively drawn to it. Shadaline's world spirit is very potent, and of a more feral nature than the Nor'I.
For a time, the Takish Empire took advantage of the kerrans' presence there, using them to harvest resources such as precious plants and herbs which were particularly useful in making medicines and poisons. House D'Vinn had a mutually beneficial alliance with the kerran tribes on Shadaline, until an unfortunate incident damaged that relationship.
