The main feature of Illte is its continental ocean Tejmokh. Being most of the continent it contains most of the flora and fauna of Illte, and has become a vital source of food. As there is no separation between Tejmokh and the ocean outside Illte, the water is salty and not a natural source of drinking water.
Other notable natural features are the fact that Illte has no bees. As such no plants requiring pollination by bees can grow on the continent. The source people found that out, almost to their destruction, when they planted the cere and trizere they brought along with them.
In the interior of the continent there are also a few volcanoes.
