Publisher's blurb: Mega Tiles are just what the name implies: really big geomorphs compatible with Dungeons in Blue tile sets. Each Mega Tile is a single geomorph covering four times the area of a standard-sized tile. These larger tiles allow bigger caves and chambers to be depicted, and also serve to break up the gridded feeling geomorph-based dungeons can sometimes have. Mega Tile Fourteen is a large cavern crossed by several chasms. Someone's gone to the trouble of putting up a few bridges and minor walls to protect these crossings.
