Seed for Minecraft 1.18.2 will take you to the center of a desert village on the island and right in front of your eyes there will be a destroyed portal that will lead you directly to the walls of the Nether fortress. You will only need to get the missing blocks and activate the portal using a Flint and Steel or Fire Charge.
