This unique greathammer is the signature weapon of Eslo Lightfoot, and was made by his late friend Eddard McHayden from the head of a maul used by a Giant sheep rustler the two apprehended while they were adventuring together, the head of which turned out to be a meteorite, hence the Shepherd's Crook being made of extremely rare star iron. Now in Eslo's older years though, it is more commonly used as a walking staff and, unsurprisingly, a shepherd's crook.
