Not too long before the PvP Rounds, Heart Heater bought The Memory of Cintamani form a wanderer. 
'여의주의 기억' literally translates to "Memory of yeouiju" . Yeouiju is the Korean pronunciation of the Chinese word ruyizhu (如意珠) (lit. "as-one-wishes jewel"). Ruyizhu is the Chinese translation of the sankrit word, Cintāmaṇi, which means "Wish-Fulfilling Gem" . So ultimately, 여의주의 기억 means 'Memory of Cintamani'.
Line Webtoon correctly translated this as 'Memory of Cintamani' in Episode 1. However, they have since called it 'The Memory of the Dragon Pearl' since Episode 143. The reason for this is most lilel;y because in Korean mythology, a Korean Dragons are depricted carrying the Yeouiju (this is explained in more detail in the Notes & Trivia section).
Ultimately, this wiki will always go with the true and original meaning, so 'Memory of Cintamani' has been retained.
