The Nameless Urn (名無しのつぼ, Nanashi no Tsubo, Nameless Vase) is an item in the first Suikoden. The Nameless Urn is a quest item needed to recruit Jabba in Rikon.
Suikoden
Jabba, an appraiser in Rikon often boasted that he could appraise any item you brought to him. If he ever failed, he would offer to do anything the person asked. Although supremely confident in his abilities, one Rikon resident noted that one time Jabba failed to appraise an item: The Nameless Urn.
Tir McDohl was able to obtain a Nameless Urn on the plains of Kunan and when he stumped Jabba with it, recruited him into the Toran Liberation Army.
