Some worlds

A world built for discovery
Your imagination is the interface.
"This is mudding the way it used to be. And we like it like that."
Out of the ruins of Old Thalos City emerged Merc's Midgaard, the heart of the Hidden Worlds. Its environs are inhabited by the creatures of fantasy and magic.
Hidden Worlds is based on Merc/Diku mud code and has been online since 1992. Some areas have been kept from the original Merc world for players familiar with them. If you like the Merc system, then you will love us.
The world keeps growing. This fall brought three new areas to explore, NPCs that hold real conversations, and a full alias and macro system. Our creation team works to keep the good old Merc Diku feeling with new and custom areas.
We support limited player killing, clans, quests, marriages, chaoses and lots of hack and slash. Quests are discovered out in the world, not handed out from a list. There are more adventures to enjoy than we can quickly describe, so come and experience them for yourself.
Join us and journey through the Hidden Worlds of your imagination.
