So here's the Plan
We need Coders and someone who can edit/minipulate/create mods/plugins to Create A server with multiple worlds (I'm thinking around 3-5) and unique texture packs.
and a 200-500 player server, The Server is based off of Premade Factions (Legionnaires, Elves, Pirates, ect...) that will battle each other.
You can have Multiple Classes, Ender Chests are a good way to send stuff to a different character of yours.
There will be multiple worlds
Alien Mother Ship (Aliens are dead from start and used as an excuse to add a portal room)
World 1: (Member) (Free)
Natives - Standard Minecraft World with edited Mobs ( SO MUCH STEVE )
