This large spawn/hub has up to 9 possible portals and 2 central parts (one small and one large divided in 4 parts). It features an underground golden cave made out of rocks with massive tall structures around its center lake (mostly supporting the huge rocks).
It has a build-in parkour that goes from the very bottom to very top of the cave.

This makes up for a perfect main spawn/hub for your medium/large-ish server !

The schematic is rather heavy and will cause a lot of light update, so I advise you use mcedit when trying to implement it on a map (plus since it's almost 256 high, you wouldn't want to paste it twice or more to get the proper pasting height).

Feel free to contact me if the need arise, Zej.
