For Abandonia users only
Darth initiated the world by flooding half the map and Vatx quickly created an Abandonia logo:
Halindir has made a pretty awesome fortress with cool walkways and there's even a "secret" tunnel into the basement of my house
Occasionally, I have to restart this server, so it may not always be up (have some patience if it's down), but I'll soon migrate it to one that is always up. When I do that, I'll also add a Minecraft Alpha server.
