Used this map tonight. The PCs delved into a hidden temple beneath the library of Ghendarthic Engravings deep in the swamp near their hometown. They hoped to find a watersource that could enhance their magic. Indeed they found such a thing but only after fighting a shit ton of slimy orcs and their mage masters. It was a bloody running battle and some of their henchmen nearly perished. I inherited a level 8 campaign from a DM who needed a sabbatical and I have to tell you mid level play OSE is pretty fun. The Wizard dove into the pool headfirst and is now being tutored by a tentacle monster.
Next session is going to be a tussle with some giant ants using a map I posted earlier. I love Dysonlogos.
