Worldbreaker was a massive bombard finished in 2009 AR by the foundries of Alkenstar. It was commissioned by the nation of Taldor for its Fifth Army of Exploration. The largest known cannon to date, its bore measured an unbelievable 30 stone (roughly equivalent to 90 inches). After it was decommissioned, it was placed on a hill in order to guard the western approach to the city of Oppara. The name of that hill remains Worldbreaker Hill to this day. It was recommissioned for the Sixth Army of Exploration, who dragged it across the continent of Garund. It was lost there in 2089 AR in the Battle of Nagisa against the Gorilla King. It is said to now hang in the treasure hall of the Silverback King of Usaro.
