Iychtor is a large, mostly frigid planet. It is mostly covered with glaciers although there is an immense frozen ocean. There is a very diverse temperature range across the planet. The few patches of greenery that exist on this large patch of ice are the result of underground volcanic activity. In the spots where the magma resides close enough below the surface, there stands isolated vegetation and animal life. There are large rock formations along much of the coast of the ocean as the molten rock pushes its way up upon the glaciers. One of the most interesting points of interest is the giant pools of open lava surrounded by glaciated plains.
