Looking for mod - NPC ally?

[Thundercraft]

I just wanted to ask if there exists a mod that can add at least one "human" NPC ally (even with very limited AI / functionality) in order to serve as a sort of substitute for another player and help out Single-player players. Most of the time, I don't feel that playing multiplayer is worth the hassle or headaches. I'm more comfortable playing single-player, anyway. But this game feels to me like it was designed, primarily, to be played multi-player.

So far, the only mod I've found that may be remotely like this is "BasicNPC". However, it sounds like that NPC is an enemy, described as a quote, "single mob/NPC named Ned". (Also, it looks like it hasn't been updated since 2020 and I'd imagine that it would not work with the current version of the game.)

The only other NPC type mod I've found is "Mutant Crawlers Infestation". But, obviously, that just spawns enemies to fight.
