Tolguth, like Icestair, is situated at the foot of the Crown of the World, but it is a surprisingly warmer place, and great tropical ferns, rhododendrons, and cycads grow in the deep delving valleys carved by the glacial moraine. The land is warmed by hot springs and volcanic vents that run through this part of the realm, and the valleys are filled with great sauropods, ceratopsians, and duck-billed dinosaurs. The area is also overrun with predatory creatures, ranging from flightless terror birds and hot-blooded raptors to titanic tyrannosaurs. As a result, Tolguth is a walled settlement, although creatures commonly breach those walls.
The greatest danger to Tolguth is not the native creatures, but the strange and twisted creations that spill out the Worldwound. Just as the western reaches grow colder under the enchantment of the Witch Queen, the eastern border comes closer with each passing winter, and someday Tolguth itself fall under its spell.
