I got a new mod called the invasion mod, and I thought I could submit my towers for this mod. So I decided to get started and make the Worshippers world. This is complete with bedrock lining in the walls to stop monsters from breaking through, door box traps, watch tower, archery defence above the walls, and a fancy interior!
It's meant to be for the Nexus Worshippers who bow to the nexus, since it's an extremely valuable thing to have.

Additional Notes

Ever played tower defence on Minecraft? If you haven't, Try it with the invasion mod! If you have, Use this world and see what it's like!
