Anomalous Dimension

This concept features a new end game dimension that will be very rewarding but also very risky. The portal to this dimension will be crafted with a new item called "Anomaly Fragments". These fragments will be found deep underground in a large open rooms. Using 8 Anomaly Fragments and a gold block the player can craft the "Forged Anomaly". When placed on the ground the Forged Anomaly will teleport all players in a ten block radius to the new Anomalous Dimension destroying the Forged Anomaly in the process.

Once entered the players will fight through long and twisting hallways with large rooms in between.
The rooms will feature chest and on the rare occasion blocks of emerald/gold/diamond. Some rooms will also spawn with a special enchanting table that will grant a free enchantment.

When entering this new dimension players will also notice a boss bar at the top of the screen titles "Collapse" that acts as a timer. The timer lasts 30 minutes, when it ends all players still inside the dimension will die and lose their items for good. Multiple Forged Anomaly blocks can be found inside the dimension and when mined will only send that player back to the overworld.

When a Anomalous Dimension is open using a Forged Anomaly will send you back there. Once the dimension collapses you will not be able to access it again you will only be able to open another one. This will add a fun endgame built around combat.

All feedback is welcome as I'm considering modding this into Minecraft.
