Dynmap

As the name suggests, the midgard Dynmap is a set of detailed maps of the various parts of Midgard: Overworld, Nether, End, Creative, War World, and the Island.

The maps are dynamically updated in real time, and can show: These options can be set with the "layers" button in the upper left coner of the map.
 * player locations
 * grief prevention claims
 * player homes
 * custom markers
 * the world border

Different dimensions as well as player icons can be found in the expanding panel on the right side of the map. Clicking on a player icon will center the map on that player. Clicking on your own icon is a great way to get oriented on the map.

Markers on the Dynmap can be purchased with diamonds by talking to an owner.
