I just added the Thingstead and the Temple as separate mods for vanilla. The temple works with just firewood unlike in North7. It has no circle because covering the whole map.
The Mead Hall I’m not sure yet how to make it vanilla compatible, with mead requiring honey requiring beehives and the completely different alcohol and trading balancing in vanilla. It might follow later. The temple serves as compensation. ;)
