Wreck Hunting in the Vile Fens

So I've been thinking a little about the Livid Fens, and area well South of the Anomalous Subsurface Environment Megadungeon on the Land of 1,000 Tower's 'world' map.  The place is sketched in ASE 1 as a weird red swamp filled with dinosaurs and froghemoths, undoubtedly irradiated.  I've expanded it with hints as the home of human tribes people, a necromancer witch queen and the site of ancient battles. 

Map W-1 of a "Weird Wreck"

Indeed, the Livid Fens are filled with monumental rusted war machines from the wars after the fall of the ancients.  Strange cults, mad dictators and radiation mad battalions in clanking steel tanks of dungeon size all perished in a mutual orgy of nuclear, chemical, thaumaturgical and biological mass destruction.  The remnants (The Red Demon being a medium sized one) still provide interesting adventure locals and offer places for salvage. Below is a small wreckage map and a table of treasures for within.  Note: I have a separate table of perils, but since my ASE game may make it to the fens sooner or later I don't want to give too much away.
