This map was originally intended for use in a pulp Savage Worlds game, but that never got off the ground.

The idea is that these lands were ripped from our world and now exist in an alternate plane that can only be reached through the Bermuda Triangle, navigating through some treacherous waters at particular times of the year when certain stars align.

This was created mostly in Photoshop using a Wacom Intuos 4 tablet. I did scan a folded sheet of paper to get the crease marks in the map.
