Aging World 

 

This is a very old planet. Since many billion years, uncountable creatures of strange kind roamed this world, only to be replaced my more advanced forms. But now, one of its parent stars is ready to leave the main sequence, slowly evolving off to a red giant. Over the course of the next few hundred million years, this planet's climate will eventually shift towards an ever warmer desert, forcing life back into the oceans, which will become warmer too...
This world is doomed to die. If it is home to intelligent beings now, they are best advised to leave their planet now, before it will be too late.
