An interesting seed that will allow you to find an incredibly small stronghold. It has only one room, which contains a End portal. To find it, go to the coordinates 1455 ~ -730. In addition, right on the spawn you will find a large cave, which can be made a starting base. Next to it, a lava flow falls into the water, which will allow you to quickly get obsidian and make a portal to the Nether.
