Suppose on April 1, 2016, the online game Runescape launched a new in-game quest called 'River of Blood'. The quest is the longest quest in Runescape, taking players roughly 3 hours to complete, and it is set in the city of Darkmeyer. The quest involves players aiding the Myreque in freeing the city from vampyre control and culminates in a battle against the vampyre lord Drakan.
Can we infer that "The 'River of Blood' quest was released on April 1st, 2018."?
