Im sorry for the vulgar language but the seed is: FuckThePolice
This seed has everything you need.... its on an island with alot of cool stuff i suggest taking 5 minutes to run around it in creative mode there are many ships and a couple tower strongholds with items in chests including a rift blade! im keeping the locations secret but you can find them easy and a little ways off the island you spawn on there is another larger island.... i beleive i found atleast 5 different biomes and a cool lake near spawn.... Let me know if you think its as cool as i did.
(P.S. sorry for the wall of text)
