Three Small Islands with Temples Seed

This seed starts you on a small desert island in the middle of the ocean, with two smaller islands nearby. Each of those islands has a desert temple on it, which is a rare setup that gives you access to temple loot without leaving the immediate area. One of the chests has three diamonds, and the others contain horse armor, emeralds, and other useful items. The closest temple is at -136 ~ -168.

There are also sunken ships in the surrounding waters for extra resources. It's an isolated start with no mainland nearby, so you're working with limited blocks and no trees on the islands themselves. But between two temples and the shipwrecks, you'll have strong loot before you even need to think about finding the mainland.
