The most expensive export of the Rin archipelago, the bottled winds are sold anywhere a buyer can be found.
The Sea hides many secrets in its depths, here are 30.
The grudging gift of thankful mermen, a fine blade with a bit of baggage.
Deep within the heart of the Great Woses, lies an inland sea that few care to visit. Nevermind the ogre-infested swamps that surround it, the place is just disgusting. While known by many names – the Belching Sea, the Eternal Loogie, Gluumraag's Blessing and sometimes, the Slimy Deep – most simply call it the Sea of Snot.
This is a wretched tome of oceanic blasphemy; a foul water-stained, bone-white binder of bitter dead-men’s secrets and a guide to Nautical Necromancy useful in the hands of the young sea-faring necromancer or the Great Lich Umeen herself.
The local band of 'nasties' (goblins / orcs / whatever) lives in relative peace with the local population.
Along come the PCs and go through their usual heroic monster bashing routine, wiping out the nasties and pinching all their stuff, then continue on their way.
Problem is, they don't kill ALL he nasties. The survivors want revenge and, after spending a few months recovering, start to take it in their own inimitable style (which is not unlike that of the PCs come to think of it).
Next time the PCs are in the area they find themselves VERY unpopular with the townsfolk.
