A magic medallion is central in Michael Ender novel, and it is depicted as two snakes biting each other, in a loop. Folk tale says that the design of the medallion changed for the Wolfgang Petersen movie, depicting an even deeper image of infinity. The medallion turned out to be an icon for the story fans. This paper will unleash a broad view of the realm of requirements and requirements engineering, comparing it to Percival quest for the Holy Grail. Using literate and pop metaphors the paper posits that requirements engineering is an education process, which must be performed with transparency. Historical misunderstandings of requirements are reviewed, pitfalls to avoid are signaled and new trails to be built are proposed.
