We slew at least 9 of them and the rest fled. We ran through the badlands and Rayne remembered an ancient Dwarven hold back to the South. He found the hidden portal and we concealed ourselves within. Several hours later, the orcs and wargs came - more than 200! They searched day and night, but couldn't find us. The orc commanders started getting really pissed.
Rayne began searching the halls and found a secret door! It lead down a hall to a ladder that lead up into the darkness. We waited a few days for the orcs to leave and then we followed the ladder up to the top of the cliff. We marked the location in our maps.
