Session 2: Rescue Greenest villagers and deal with a dragon? Report

"The guards have spotted a new threat. Raiders are trying to set fire to the town's mill. If it burns, we'll lose our stockpile of flour and we won't be able to grind more for months. I'm trying to assemble enough defenders from here in the keep to defend it through the rest of the night, but that will take time. You'd do us a great service if you could get to the mill quickly and drive away the raiders before they can set it aflame. You'll need to defend it until our force arrives to take over, but it shouldn't be more than fifteen minutes behind you."
The party headed into the tunnel with Lorilla leading the way and Nivek helping guide.
The group came upon two nests/swarms of rats and decided to clear them out so that any villagers they sent back would be safe from them. They did this with Lorilla throwing some "cheese" past the rats and then the group attacked while they were distracted.
The party made it past the rats found an old corroded gate and lock. After some resistance the lock gave way and the party made it past, locking it behind them.
Making their way though town they came upon 6 villagers hiding behind some crates and refuse. They also saw a group of raiders about to stumble upon them.
Deciding to draw the raiders away from the villagers Tanaelia ran to a nearby building. Upon opening the door to the building the raiders noticed her and ran after yelling "Get her!"
A fight ensued and Tanaelia started lighting the building on fire.
The raiders wounded Tanaelia, but she quickly healed herself and the party dealt with them quickly and one ran off.
The party led the six grateful villagers back to the keep safely, narrowly avoiding another raiding party in the process.
Arriving at the keep they were greeted by Castellan Escobert who told them that Governor Nighthill wanted to talk to them.
Nighthill told them, "The guards have spotted a new threat. Raiders are trying to set fire to the town's mill. If it burns, we'll lose our stockpile of flour and we won't be able to grind more for months. I'm trying to assemble enough defenders from here in the keep to defend it through the rest of the night, but that will take time. You'd do us a great service if you could get to the mill quickly and drive away the raiders before they can set it aflame. You'll need to defend it until our force arrives to take over, but it shouldn't be more than fifteen minutes behind you." And the party agreed to help.
