Isle of Dread, 4 miles per hex
“When the gale finally ended, we found ourselves approximately seven days normal sailing distance due south out of Specularum, in the Thanegioth Archipelago. We replenished our supplies, patched up the ship, and traded our remaining goods at native villages along the shores of several islands. Some villages were friendly, but others were hostile and the natives attacked on sight. I suspect the hostile villages were filled with cannibals.
“We skirted the coastlines of several islands, sailing south by west until we reached a small peninsula cut off from the main island by a massive stone wall. We were well received by the natives of Tanaroa, the small village that guards this wall. The villagers have no name for the large island other than the ‘Isle of Dread’. Their own small peninsula is known simply as ‘Home’.”

Comments
I first created this map back in 2006, and it has seen surprisingly few updates since then. The latest version is from 2020, when I added some of the early results of my Let’s Map Mystara project — not least of which was the reinterpretation of the scale to 4 miles per hex. This allows the map to match the 24 mile per hex map of the area.
It remains in need of further development to incorporate later official (Paizo) and fan-made maps.
Notes
- Denizens — This map combines the encounter monsters from both the 1981 and 1983 versions.
- Jungle Hills — Almost all of the hills on previous maps have been changed to jungle hills. This symbol was only introduced very late in Mystara’s publication run, but it seems more appropriate for the Isle of Dread than bare hills. The caves have likewise been changed to jungle hill caves.
