Ember's Castles And Keeps
by ember_slvtr
With Ember's Castles And Keeps installed on a server, the world gains large castles, towers and keeps that hold traps, enemies and loot, along with parkour challenges at their tops.
What it does
Ember's Castles And Keeps adds new structures generated in the world: a gigantic tower that looms over the landscape, a small abandoned tower, and a medium tower standing alone in the middle of nowhere, filled by an undead horde. Illager mages prepare raids from the Pillager Tower, an undead castle is infested with zombies, a rare desert tower hides dangerous undead monsters, and a villager keep, a giant fortress, is home to villagers who can be greeted.
The castles and keeps are the latest addition to a mod series that adds five new dungeons to the game, with more still in work and updated continuously. The mod is server-side only, so players join without installing it; the server alone runs it. Installation targets Fabric, Forge and NeoForge, with builds for 1.20.1 – 1.21.4. The license is All rights reserved, so the mod is not open source.
