If you want to create a universe that’s fairly rich in habitable worlds, and you’re venturing out as far as the 25-30 light year range to tell your story, it will be a bit boring to have all of them orbiting G or late F stars.  So here are some K stars to put into the mix.  Where I could find them, I have included age and metallicity info.  None appears to have any known planetary companions.

Gliese 673:  a K5V star in Ophiuchus, apparently more than twice the metallicity of Sol, 25 light years away.

Gliese 884: a late K (or possibly early M) star in Aquarius, 27 light years away.

Gliese 250: a K3V star with an M companion hundreds of AU distant, in Monoceros, 28 light years away.  ETA: Beichman et al give this star an age range of 9.02 to 9.82 billion years, with a metallicity around 1.15 times that of Sol.

Gliese 183: a K3V star in Eridanus, 28 light years away; close to Sol in metallicity but may be only 2 billion years old.

Gliese 785: a K0V star in Capricorn, 29 light years away.  Metallicity just a bit lower than Sol’s; probably 7 to 8 billion years old.
