This is the world from my YouTube Let's Play series, JimmyUltima Plays Minecraft. Here, I started a new Vanilla world in 1.8.1 and went on to do some fun builds and adventuring. The world download is up to date a little past Episode 50 using version 1.8.5, which was a Grand Tour of what I have accomplished to that point.

Within the Base, it is broken up into several sectors, each containing a variety of different builds, as well as a Nether Hub and things outside of the Cave.

Currently, there are 5 Main Areas within the Cave Base.
Original Base - Where everything began when we first found the cave system, with the floor made of Birch planks.
Expanded Base - The first place we expanded into, with the floor made of Dark Oak planks.
The Mines - Smallest portion of the base, but has access to a good mine, with some of the floor made of Acacia planks.
Lake Zone - Perfectly place underneath our lake, we continued to expand over there, with the floor made of Oak planks.
Sky Base - With the intentions of building in the sky, the base has begun, with the floor made of Spruce planks.

There are also 4 areas out of the cave that are used frequent
Snow Fortress - A place that is cold and everything, perfect for the gathering of Ice and Snow.
End Base - A place that connects the our Nether Hub to the End, including The End itself.
Desert Outpost - Our first and primary option of Sand Gathering.
The Nether - The Dome has fallen on us to keep us safe, except we can escape it easier, but still be safe.

The world that our server has now started, we started out with Snapshot 14w28b, and then updated it to the 14w30c snapshot to include some of the new things, mainly for performance, as well as banners, then bumped it up to the 1.8-pre3 pre-release snapshot, and now are running it on the 1.8.1 official release. Those who have contributed to this server include myself (JimmyUltima), GSKev, and TheDrewMan2

We spent a long time using Admist to find a seed that fit the needs of everyone, that included a nearby Mesa, and a decent sized island. The world spawn was changed to be on the island at 0,0, and we all went from there.

Currently, there are 4 Main Areas on the Island
JimmyUltima's Super Base - includes 7 Floor Wheat, Potato, Carrot, Cow Farms, Sugar Cane Farm, Poppy (Iron) Farm, Log House, Village, and Blue Beacon
GSKev's Market District - includes Chicken Farm, Wool Farm, Charcoal Farm, Fishing Shack, Modern Home, Potions Lab, Library, Starting Base, and Grey Beacon
TheDrewMan2's Watch Tower - includes Watch Tower Home, Multi Level Slime Farm, and Green Beacon
Spillman88's Underwater Base - includes Underwater Base, and Small Horse Stable

There are also 2 Main Areas off of the Island
The End Base - includes The End Portal and Stronghold, The End Fortress, and anything built in The End, including the Ender Ender
The Snow Fort - includes The Igloo, and Ice Farm

All of the areas are eventually going to be connected by the GRLHS (Get Real Lost Highway System). As of now, it connects JimmyUltima's Super Base, GSKev's Market District, TheDrewMan2's Watch Tower, and Spillman88's Base, but it will expand from there to circle the full island. Construction for a Boat Travel System to The End Base is also being planned
