Nertle the bard, Lydia the fighter, and Kreepto the kobold come out of the tavern behind your group after a few moments. The three of them seem to be together, and they walk up to your group at a steady pace. When they arrive, they announce themselves...
"Kreepto knows where your going. Kreepto should come too. You won't navigate the mines without Kreepto, and you won't know where to go."
Lydia smiles a bit and then explains her reason for coming, "And you won't be able to get into the encampment without me. I assume you all have enough gold to take up an inn for the night, right? If all of you stay in at Uther's, over there..." she points down the street towards a large building, "we can meet up with the caravan heading out tomorrow. It's your best bet for making it into the fort unnoticed, but it'll cost you 5 gold pieces a head. Nertle here already paid for four of you."
Nertul, the uncharismatic bard looks stunned, "You... you said that it would cost 25! You lied to me Lydia!"
Lydia offers a wink to the group before she tells Nertle to be quiet. "Nertle's just a tag-a-long, he never let's me have fun without his incessent following." She returns to talking about the offer, "So what do you say? You willing to pay a little to afford yourselves some stealth? I don't think you could get past the gates without it..."
