[@Mae] Einkel seems to me to be very much the kind of person without any real goals in life. He's happy with the way things are. His work is interesting and he enjoys it. Some dwarves might be obsessed with things like becoming better at their trade, or completing their life's work. For Einkel, he's content being pleasantly surprised when he makes something wonderful.

That said, I would like to see one of two things occur. Either the quest twists his body, rousing his dwarven instincts and that ancient pride, and he feels compelled to master the command of his form. (I.E. he becomes a powerful moon circle druid)

Or, the influence of the magic changes his spirit. It opens his mind to the greater world around him, and that contentment to be what he is grows and blossoms. Instead of being a simple moonshiner, he becomes a part of the marsh. He joins the circle of the land, and will eventually become the arch-druid of Dreadmorasse. (Basically, he turns into Radagast the Brown).
