Seed: -1256747364
This is probably the best seed i've personally ever stumbled on for 1.14
you start off between a villiage on the edge of a dessert with a dessert temple behind it. Villiage has iron workers so you get some decent iron out of it along with leather.
The area has very numerous caves and a cavern and theres is also a rocky region with plenty of coal.
Just next to the rocky region theres a shipwreck right on the beach.
Lastly, just off the shore and not too far from the first shipwreck is a second. If you turn arround while here, you'll also see an ice realm behind you
Also found:
1) about 30 blocks to the north west from the start point is a rather small cave going down, follow it and you end up in a mine.
2) second temple in the desert biome with another villiage.
