Adventure 2 Dungeon world, exploring the skaven tunnels

A quick synopsis of the high points:
Short game.

The  Party descended into the  ruins of Careth, using an old sewer pipe that The Master had found  the day before.
The party soon realized that the ruins are quite literally a rat warren of tunnels and Piled debris, left over from what ever cataclysm befell the city.

Johann found two  brass pieces that had been mangled but still clearly  held engraving s of  very old gnomish runes.

The party found that the skaven are skirmishing  fairly regularly with a group of Nagga who seem to hold the  center of the  ruins.

The party also found that the skaven seem to be pretty  cowardly and malnourished.

Several skaven were easily overcome, including tow that were mauled to death by the master in bear form.

A cistern was crossed with  much difficulty and  one wounded Gnome.

The party followed sounds of battle coming form a group of skaven who had had caught three nagga in the unusual position of beingout in the open. The skaven were attempting to take the Nagga down when the party joined the fight on the side of the Skaven.
(The consensus is No one likes snakes so .. sides are taken.)
(The skaven for their part scattered when the party arrived, not wanting to risk fighting on two fronts.)

The  fight was not easy but the party took the three Nagga were defeated leaving the  Party to collect themselves and figure out exactly whats going on.
