Abyss SMP

Abyss SMP is a Towny server built around exploration. The map is fully custom — an ocean of islands, ruins, and structures made for this server and nowhere else.
Sailing out is how you get ahead. Custom items and loot are hidden in those structures, and what you drag home you can put up on the player auction house. The economy runs on what players find, not on admin shops, so a good expedition is worth real money.
Claim land and found a town, or join one that's already standing. There's lore running under all of it for anyone who goes looking.
PvP is here if you want it, and easy to avoid if you don't. Custom events run regularly.
