A Dragon Egg Holster.

Middle of the second day of our brief time to rest and prepare for the upcoming events. Howard is spotted flying in the air with a piece of parchment in his talons. He spots a few members as they run around town with their own errands. To each one he gives a look of acknowledgement but continue his flight until he see Elly. Swooping down landing in front of her on one leg. He raises the other with the piece of parchment and gestures it toward her. The letter reads, "Dear Elly, I think I found a solution to keeping your egg safe. Stop by Mimzy's shop and on the counter top will be another pieces of parchment, a bag and a metal structure for you. I'll most likely be preoccupied but I left everything you needed there. Your friend Fenthwick Fizzlebang" After Elly read the letter Howard lets out a hoot and flies away.

Elly smiles when she sees the owl flying her way.  She raises her hand in a wave, calling out to him, "Howard!"  Howard lands and presents her with the parchment, which she carefully unties from his leg, petting him gently and thanking him before he takes off again.  She reads the note and eagerly heads to Mimzy's shop immediately. Once inside, she doesn't see anyone right away, and assumes that Fenthwick and Mimzy are spending time together.  She gathers up the items and, in case the gnomes are within earshot, she calls out loudly, "Thank you!!"  She then happily leaves the shop.

You see an upside birdcage like structure with springs lining the inside of it, a bag holding 15 gp and two pieces of parchment. The note on top reads  "Dear Elly, This structure is far from complete you need to fit it with some leather, wool and a nice fabric to cover it all. I think the seamstress in town may be able to help you with this. She was quite nice Howard said. While you're there could you be so kind and pick up my robe I had commissioned for, the bag should hold enough gold for it. The second page contains the sketch of the final product and measurements. Good luck! Your friend, Fenthwick Fizzlebang" The sketch shows an exploded view of the holster. Starting with the out layer going inward : Thick Leather, metal birdcage, springs, thinner leather, thick wool, fabric covering the wool. Fenthwick wrote on the fabric layer Cotton? Silk? Linen?. Below the exploded view it shows a few modification you can make to it once the egg hatches. Which will allow the dragon to sit comfortably in there but will only last until it outgrows it.
