Story so far ...

Still onboard the airship, the party is attacked once more by a dragonrider. Their combined might makes short work of him. The party then has to defeat the crew of the Sacrifice, another airship that tries to commandeer the ship the party is on. The party then continues their journey and crashlands on the cliff above their destination. After defeating the guards, the party can set off an avalanche that crushes the assault of the enemy vessels. After making their way down, the party fights the attacking forces amidst the wreckage, stopping a rituel that would have gained them entrance to the besieged city.
