"What is it, the Ring of Erreth-Akbe? Well, you can see that it's not precious looking, and it's not even a ring. It's too big. An arm-ring, perhaps, yet it seems too small for that. No man knows who it was made for."

The Ring of Erreth-Akbe is a magical object needed for peace in Earthsea once the two halves are united. It was originally the Ring of Morred. It is hard silver, covered by an engraving, nine punched holes and nine True Runes, one of which is the broken lost rune e.g. Bond Rune, the sign of peace.
Other True Runes are Pirr (protects against madness, fire and wind), Ges (gives endurance), Agnen, the Rune of Ending (closes roads, written on coffin lids), Simn ('work well') painted on tools, Sifl ('speed well'), painted on, for example, ships.
