Once around level 20 or so, head to Ashos. When you arrive there, you should accept the quest to help a woman's sister who is in trouble. After you get the Key to the Temple by completing a few other minor tasks, head into the temple itself. You will need to kill off snake enemies within that are pretty tough, but otherwise you'll want to make your way towards the main chamber and steal the treasure sitting there on the podium.

Stealing this treasure will cause the city to lose its protection from Orcs. When you get out the Orcs will have killed everyone and you can loot the entire town. Combined, you should find plenty of swords (including powerful Katanas), and around 75,000 gold.
