I've established some theme names already with my main breeding farm. Rockstars/songs and supernatural

Might go with Game related characters. Haha

I have quite a few

They range from kpop idols, kpop groups, anime characters, and book characters. I also have a memorial affix and the horses with that affix are named after people and pets in my life that have moved on to the sky. The most recent edition is a unicorn named Yeontan, named after a kpop idol's beloved doggo who recently crossed the rainbow bridge

Some of my theme names include volcanoes, types of storm and lightning, and types of hotdog

hoho what fun, another of mine is planets (mercury jupiter etc)

Oh Lord. I've done single season tv shows, characters, poisonous plants, lines out of podcasts, types of stars, goddesses (I only keep mares), song lyrics and/or titles, I did a whole Bob Ross thing for a bit.

Honestly it is just whatever takes my fancy at the time and then I run it until I'm not enjoying it and then I switch again.

I'm currently between themes.

good idea. i once called a horse commander shore after the character in stingray.
