I love getting to play with a new style! While it's more simplistic than MicroDwarf maps typically are, I think the use of the brush pen really sells it as a rough artifact. This is clearly not made by an author that particularly cares about the names of the places that were sacked, looted, and burned.
The fate of Tormugen Maw is given away slightly by the map and, ideally, the horrible tentacles or cracks radiating away from the final battle. Who won? Who knows? All I do know is if (when) I make a different version of this map, a good half of that valley will be a wasteland. So goes the fate of powerful ogres.
