Horse Cult
To put it bluntly there was an old friend of mine that got me into vintage story, but the way he got me into the game was a bit more deranged. Him and, about, six friends were playing on a vanilla server when they found a place to build this castle like structure. Only weird dilemma inside was effigies and rituals around every corner to this horse that was trapped inside a stable. I'm talking there's an entire underground church they built just for worshipping this random horse, it wasn't scrambled and put together either. This had so much detail it was breath taking, they put more time into worshipping a horse than they did building their own walls for the castle or their homes inside.
I don't have any screenshots because this was shown to me in person, if I had pictures I would share. You simply had to be there to understand what I'm talking about.
