They were part of a greater mod that I built around the weapons. I cancelled the mod because I was too busy at the time and just focused on the weapons instead.

The way I've designed a lot of these weapons is by building them in a greater context, even if players never get to see it. It helps me generate ideas. Specifically the Celestial weapons have had a lot of lore around them.

At the end of the day, however, shipping orphaned/unused files is just bad practice and one I'm very much guilty of.

And you're right, I barely had time or motivation to work on this mod in a long time. I still read comments around here though.
