The Abyssal Portal
The Lord Warden’s wife showed up to help close the portal. She brought along Sun Li, who had earlier made friends with some dwarves the Lord Warden was pressuring to clean up a gang highwaymen operating out of Raven’s Roost.
The Portal was closed and the party defeated the Abyssal Hydra which was guarding it. Their victory was largely attributable to Heskan’s use of the Rock and a Hard Place stance, with Sun Li acting as the hard place.
