Version: Java Edition 1.21.1 (compatible with version 1.21.11)
Spawn Biome: Plains / Desert
Surrounding Biomes
The spawn point is at the junction of plains and savanna. Within a radius of a few hundred blocks from the starting position are the following biomes: jungle, mangrove swamp, and cherry grove on the mountain peaks.
Structures — Coordinate Table
Since the structures are right at the spawn, you'll find them without long searches. The coordinates of key points are provided in the table:
Structure | X Y Z |
|---|---|
Plains village with 3 blacksmiths |
|
Desert village with 3 blacksmiths |
|
Trial Chamber |
|
Ancient City |
|

2 villages with 3 blacksmiths each
The spawn point is on the border of the plains and desert biomes. Immediately after loading the world, you will see the first plains village, which contains three working blacksmith shops. Nearby is a desert village, where three blacksmiths have also generated, an extremely rare occurrence for a starting location. In total, three more villages are within viewing distance, allowing you to quickly start trading with villagers.
Right under the first village at a great depth, a large vein of diamond ore has generated. By digging a mine shaft under the blacksmiths, you can mine over 200 diamond blocks without extensively exploring caves.

Underground Structures: Trial Chamber and Ancient City
Hidden beneath the starting villages is a Trial Chamber — a key underground structure in the 1.21 update. It contains new trial spawners and vaults where you can obtain valuable resources for combat.
Even deeper under the mountain range, several Ancient Cities have generated. These cities are located in the deep dark biome and contain chests with rare «Silence» armor trim smithing templates.


In the Ancient City below spawn, any careless movement can activate sculk sensors, which will result in summoning the Warden. Move exclusively by sneaking (using Shift) and use wool to muffle your footsteps.
Nether Structures and Resources

By creating a portal right at spawn, you'll end up in a prime location in the Nether dimension. Near the portal exit is a Nether Fortress (42 68 78), where you can obtain blaze rods and nether wart for brewing potions.



Nearby, a Treasure Bastion (-238 80 -119) has also generated, containing a netherite upgrade smithing template. Additionally, in the surrounding chunks at Y=15, you can easily find over 20 blocks of ancient debris.

Ancient Debris Clusters in the Nether
Upon entering the Nether dimension near coordinates X: -238, Z: -120 at Y=15, large clusters of ancient debris are present. Their exact coordinates are given in the table:

Conclusion
This seed offers an incredibly easy and fast start for survival thanks to the concentrated placement of resources right at spawn. The large number of blacksmiths and easy access to diamonds simplify early progression, compensating for the difficulty of underground exploration. The world is suitable both for speedrunning due to the convenient location of Nether structures, and for long-term hardcore survival.
