Altengah is considered the sister planet of Mortes. Appearing roughly 2300 years ago, it once was the subject of awe and wonder. Now Altengah has become as much part of the landscape as the setting sun.
Altengah has phases much like Mergo. During the day, Altengah appears a shade darker blue than the sky. During the night continents and oceans can be seen clearly with the naked eye. Usually during a full night showing, Altengah will take up as much as one eigth of the sky.
