'Careful Gradlon!' shouts Gwion, 'don't touch it!' But it's too late! As Gwion tries to take the Emperor Monteswma's ancient gold cup from his friend's hand, the cup's secret forces take the threesome - Gradlon, Gwion and Garmon - back to the 18th century, to the world of Caribbean pirates.

"Gofalus Gradlon!" gwaedda Gwion, "paid â chyffwrdd ag e!" Ond mae'n rhy hwyr! Wrth i Gwion drio mynd â Llestr Aur hynafol yr ymerawdwr Monteswma o ddwylo'i gyfaill, mae grym cyfrinachol y llestr yn dwyn y Triawd Amser - Gradlon, Gwion a Garmon - nôl i'r 18fed ganrif, i fyd môr-ladron y Caribî.
