I'm in a D&D campaign where astronomy plays a big deal. I want to name drop and reference some good astrology myths about evil or cursed stars, but I'm having an awful time finding anything. The only one I have for a reference to start searching is Algol, the demon star, which I found from an old Lovecraft story (but which has been in mythology for longer than that, of course), but that reference doesn't seem to lead me anywhere else and more generic searches yield nothing.

So my question is what are some evil stars and where can I find out more about them? I don't care what tradition or culture they come from. Honestly a mix would probably be ideal.
