Strix are magebred birds used by the Scheznyk for a variety or purposes, most commonly hunting and, most importantly, as messenger birds. They are very large, owl-like creatures with unique beard-like braids of feathers at the bottoms of the beaks. These are used to attach scrolls to by those who train the birds to carry messages.
The most useful aspects of these birds is that, from birth, they are able to sense where any creature or item they are bound to across the loom is, allowing them to carry messages across vast distances reliably. Strix are also unique in that they are able to be unbound and rebound very easily, as with most creatures such a process is straining and very dangerous.
In a bygone age Strix were used as avian assassins, sent after a target with poison applied to the claws. This practice was common during the Veiled Wars, but since the Conservator pact was made it has died out.
