I would like to see integrations added for the mod mentioned in the title.
I confirm it is available for the latest Minecraft version at the time of writing.

About the mod

Link to the mod page (e.g. on CurseForge): https://www.curseforge.com/minecraft/mc-mods/waystones

Link to mod source/API: https://github.com/ModdingForBlockheads/Waystones/tree/1.18.x/shared/src/main/java/net/blay09/mods/waystones/api

What should be integrated exactly

Display faction status for waystones in villages.

I can help with

Implementing this in a PR

Additional comments

The API has a WaystoneNameEvent which could be used here. The name is String based, so I am not sure if colors are supported.
Another concern is how to figure out if it is a village waystone (the chunk might not be loaded?)

Hmm, does not seem to be easily implemented.
The waystone API does not allow modifying the displayed name (only the generated one).
Would need some hacking or a PR to waystone.
If anyone is really interested here, please let me know (and explain what exactly you want)
