I was starting up a new world in minecraft because I got and bored and wanted to build something, and the world I was in was a big island. I thought it was a very nice island and perfect for building. I went exploring inside a ravine and found a abandoned mineshaft. I also thought if there was a mineshaft under the island maybe theres a stronghold, and sure enough there was!
Can you show the map of the surroundings? There could be other islands around it, and whats the biome on the continent?
All this is lacking to be the perfect island seed is a little jungle and a volcano
