The tunnels connect three other maps in the Index Card Dungeon – Caves Map 1, Dungeons Map 1, and Shallows Map 1. The tunnels are home to things that scurry and ooze, and a few who have been driven out of the other parts of the dungeons but not out of the complex entirely. At the far end of these caves, hidden from view from the rest of the dungeons, is a chamber with a three-tiered dais set with small stone orbs on pedestals. The orbs seem very resistant to being moved from their seats, held there by strange magics.
This is the ninth of ten index card-sized dungeon maps that all connect together. Each is designed to fit on a traditional 3 x 5 index card (at six squares per inch), and you can write up any notes about the level on the reverse of the card. The first five maps were posted last month, and the last five are being posted this month.
The 1200 dpi versions of the map were drawn at a scale of 300 pixels per square and are 9,000 pixels (30 squares) wide. To use this with a VTT you would need to resize the squares to either 70 pixels (for 5′ squares) or 140 pixels (for the recommended 10′ squares) – so resizing it to either 2,100 pixels wide or 4,200 pixels wide, respectively.
