Rival Nations: The Fall of Gods
The island of Ilstrad superficially resembles Altun Ha. The island is primarily populated by the dragon like Mokole, who mostly wile away their time in internecine warfare. Unlike the barbarians of Altun Ha, they have also proven quite capable of keeping others out. The only other race with a foothold on the island are a dwarven colony. Little is known of the Mokole, but it is theorized they were created by the Magelord Karzak, and if so, the island is worth more investigation for artifacts and documents pertaining to him.
Ilstrad is almost uniformly covered in massive trees. The mokole place their villages high in these trees,, mostly due to the jungle floor being home to dangerous predators. Any thing that lives below the treeline is generally quite dangerous.
