A shower of adamantine daggers falls through the air, tinkling all over the grounds of the fortress. At least one ton of Adamantine (someone do the math for gp value for me? I'll adjust as needed).
Note: the setting isn't Epic, nor high-level. In fact, selling them isn't as simple as going to a pawn shop. You need to find a buyer who'd want 100+ or so Adamantine daggers, AND who has the money to pay for them.
Making the magic items will also be time consuming, unless you'd just come back here and do it. You'd need people to enchant the items, unless you plan to do it yourselves.
Where to go?
Locations in the setting:
Varesia: backwoods wilderness sitting on ancient haunted ruins. Two cities of note, but otherwise lots of forests. Varisians are wandering gypsies. The cities, etc., are run by the Cheliaxian invaders (basically standard european humans whose society worships devils).
Absalom: Island city, center of civilization. A bit on hard times. Think New York meets Ancient Rome. There's a monument here that, if you enter it and survive the challenges, you become a god. Otherwise: if you can find it, it's here. If you can make it there you'll make it (ba ba) anywhere.
Irrisen vs. Linnorm Kings: two norse-style realms. Irrisen is ruled by Baba Yaga, and her snow queen daughters. Linnorm Kings (land of) is ruled by barbarian tribes who don't like Baba Yaga or her armies of trolls and giants. Lots of snow, mead, etc.
Osirion: egypt, except the Pharohs worshipped strange cosmic beings. Ergo the Pyramids are spooky.
Taldor: Think Revolutionary France. Democracy. it's so-so, but the food is amazing and the literature is fantastic. And the wine. And the countryside. And the women... Just don't show up like a pack of idiots expecting something: relax, take it in.
Ustalav: Ravenloft, basically, but not a demiplane. Evil epic lich king was defeated by a legion of Paladins, and locked up in a mountain which is now basically haunted (folks don't go there). Now the lands are covered in mists and old castles.
Cheliax: as mentioned above, but the homeland they come from. Highly civilized, lots of wealth. And, yeah, pay no attention to the fiend behind the curtain.
Riddleport: pirate haven, somewhat independent. Watch your purses.
