Packs are a type of container. The most common variety is the durable canvas backpack which everyone receives during their Trial of Rebirth in Ceylon before graduating to everyday life in Achaea. Another popular option is the wyrmskin pack, an artefact that is sold at the artefact shop, Gemstone vials of Moghedu. More recently, the wyvernskin pack and dragonskin pack were introduced at Merentesh's Shop of Wonders in Delos, as well. Some organisations sell their own special varieties of packs unavailable to non-members.
