Monks of Entrana are NPCs that must be talked to in order to sail back and forth between Port Sarim and Entrana, as long as the player has no weapons or armour.
They will allow you to carry magic secateurs, as they do not count them as a weapon. They cannot be talked to on a non-member account.
Players should note that the monks do allow runes, unstrung bows, bow strings, arrowtips, arrow shafts, and feathers. See this article for more information on items allowed on Entrana.
