About this world

This seed puts a mountain ruined portal at 48, 63, 16 in shallow water off a forested island. The broken obsidian frame stands on a patch of red netherrack with magma, next to a grey stone outcrop on the shore. Birch and dark oak forest with giant red mushrooms covers the island, and grey stone islets sit in the sea nearby.

A trial chamber lies underground at 32, -28, 0, about 23 blocks northwest of the portal. A shipwreck is underwater at 96, 63, 128, about 120 blocks south-southeast of the portal, below the steep stone cliffs on the island's east side. An ocean monument sits at 256, 63, 256, about 205 blocks southeast of the shipwreck, in open water between rocky islands. Seeder lists this world on its Shipwreck / Ruined Portal page.
