Eisen and the others just waved at the four grandmaster craftsmen and the Innkeeper as they started riding their carriage toward the right tunnel to exit town.
It was actually a little bit cramped in the back, although that was because literally everyone beside Eisen was back there right now. Once they left town, Kiron wanted to sit back down on the roof, and Bree and Sky would take over driving for most of the ride. And if he needed to, Eisen could just shrink down a bit.
But this was all just the case when considering the possibility that Fafnir was too large to fit into the carriage later on once they had him evolve. Something that Eisen was looking for a good enogh spot for currently, until he found a place with nobody really closely around, and then just stopped the carriage to get Fafnir out.
