I'm looking for a map (it was included in the pirated edition of In the Wake of Gods by Fargus).

The other day, while browsing my collection, I remembered your question when I opened the map "Happy time Dragons!!!": the description is similar; in the center, there is also an island with all kinds of dragons, but in the Dungeon, it's not a swamp, but an underground labyrinth. Just in case, take a look: maybe it's the one you're looking for?

By the way, the comments from 2 people are amusing:
"What is that round logo in the middle? Is it a game for a sick mind?"
"The logo is cool, but it doesn't fit."
People are not familiar with the Yin-Yang symbol. Poor things! ;) Although it really doesn't have anything to do with dragons...
