From the campaign:
Alliance of the Bat Week
Alliance week continues with this special gift to our loyal Norsgard fans. If you are now, or become a backer at Champion or above and remain a backer at the close of the Kickstarter you will automatically receive this model at no charge. Note that you do not need to have an Alliance of the Bat starter to get the free Wolfkin model. Every Backer at Champion or above will get one.
