|QUEST||It is not required to start any quest to collect this item.|
This familiar-looking sphere was introduced to the game with the update 10.94 on May 31, 2016 (the update that introduced the Heart of Destruction Quest along with all the Spark creatures that inhabit the mysterious Otherworld).
At that time, the item was not given any function. It was not used in any way. Perhaps it was originally intended to be part of a quest, but the game developers abandoned the idea.
A year and a half later, in update 12.00.7695 on December 03, 2018 this sprite returned in a slightly altered form, as the Ornated Sphere Lamp.
It was originally encountered on Dream Courts in the winter area. It emphasized the cold, icy atmosphere of the area with its blue light. However, it was still unclear how to get the sphere itself separated from the ornated column.
❝ Concerning how and when the sphere became obtainable, I remember it very well. In 2019, when CipSoft was reevaluating the list of contest prizes with fansite admins, I suggested adding the sphere to the list. It seems the content team liked my proposal since they allowed fansites to award the blue sphere from January 2020 onwards. ❞

Indeed, since then Blue Sphere can only be obtained through contests organized by both CipSoft and official fansites. Good news for those who are reluctant to participate in such competitions: Blue Sphere can also be purchased through the Market! Unfortunately, due to its limited sourcing, the price of this item is in the tens of millions.
