All "first 24 hours" backers receive this Add-on for free (one per each Core Box) - if you are a first day backer, with Kickstarter backer number lower or equal to 16518, you'll get an Iron Dragon without added cost. Do not add him to the order (unless you want to get more copies). He'll be added to your order in the packing stage, even though he won't appear in the checkout/order page!
