Thunderlizard Island is an uncharted island located in the north east of the The Northern Reach. The island is completely uninhabited, at least by sentient species, though it i rich in animal and plant life
The most impressive of it's native fauna are the gigantic Thunderlizard's. These lizards, which can be the size of large houses, are mostly extinct in the more populated parts of The reach, but here they dominate the island in diverse glory.
In addition, the island was not always uninhabited, there are remnants of strange temples and buildings, mostly swallowed by the jungle, that must be thousands of years old.
