In-game description
"This long bow is marked with the seal of a sunburst.  It probably once was a bow used by guards in the service of the god Amaunator.  These guards would use the enchanted bows to keep the priests of that long dead faith safe.  Few of these bows still exist, so they are sought after by many archers looking to improve both their accuracy and their lethality.  This bow requires a strength of 18 to use."
