This mod adds pins and emblems (14 so far!) some of which have been themed on the Civ genre of Minecraft servers (www.civwiki.org) and are kind of references for those players, but they're also just to add more variety and more things to collect/wear. They can't be crafted but can be found at traders.

If you use the Achievements mod (https://mods.vintagestory.at/show/mod/9615) this also adds an achievement related to collecting the pins.

The civ nations included so far are Icenia, Mount Augusta, Commonwealth, Gensokyo and Yoahtl. Also has pins for the book collecting group the Maester Alliance.

(The items aren't placeable, the images are via the place every item mod https://mods.vintagestory.at/pei and adding the items to pei's config.)
