Assassins of the Iron Cage

The assassins of the Iron Cage are the best known assassins guild in the world. Their members apparently have no thought behind their eyes other than murder. They're duty bound and have no reasoning of their own volition. These assassins are called the Songbirds.

Their members carry octagonal coins made of iron. One side is blank, while the other side displays the image of a songbird. The coin Axl woke up with had the image of a Lyrebird. The coins of the 2 assassins send after Axl had the image of a Robin and a Nuthatch on them. These coins can be exchanged for a lot of money at the right place.
