You spawn and at y lvl 40 where you spawn there is a skeleton spawner for the easy xp farm. There is also a huge mineshaft where at one point there is 2 cave spider spawners close to eachother for a better xp farm. Within 1000 blocks there is desert temple, taiga npc village. I spawned into this world using Yolo as the seed and hve yet to discover the rest of what this world has to offer. But to anyone looksing for a seed that gives a decent plain spawn with skeleton spawner this is it.
