Solar systems can have their own distinctive features, whether these be because of the star or stars in them, the planets or lack of them or other oddities. This supplement has 100 such features to make a planetary system stand out from others. Some of them are definitely dangerous, others are odd in one way or another. Some can be used as adventure hooks as characters investigate what they find.

Signs of ancient construction can be found at various points in the system.
