The Angels Nest
The Angels Nest was created in July of 2014 on Fur Affinity. This page was specifically started by a professional concept artist, known as KwiK, who wanted to help create unique designs for the Angel Dragon community. It is an officially recognized adoption page.
Every week (or bi-weekly) there is a new design that is planted in the angels nest. Visitors are allowed to bid on the design in order to win the rights to that Angel Dragon. Every dragon design is pre-approved by Ino before being auctioned off to the new owner.
In addition to the Fur Affinity page, the Angels Nest has a Patreon which offers Angel Dragon lineart templates. Anyone who pledges even $1 has access to all the templates located on the Patreon page. There is even a reference sheet available along with holiday themes, icons, badges, and a lot more!
