The conceptualization of Tales of Mysteria began in December 13, 2009 and was firstly named as Tales of Time. The story of Tales of Time was written during the timeframe of April 2010. But the storyline was not that good; therefore it was discontinued in August 2010.
On February 26, 2011, Tales of Time was renamed to Tales of Mysteria. All of the members of this series agreed to the changes and it was pushed forward.
Tales of Time is divided into three parts. The first part was simply called as Tales of Time. The second one is Tales of Time: Last Stand, while the last part is Tales of Time: Distortion.
Originally, Tales of Time contained some characters from different "Tales of" series and other series. The cameo characters are Lloyd Irving (Tales of Symphonia), Nanaly Fletch (Tales of Destiny 2), Leon Magnus (Tales of Destiny), Harold Berselius (Tales of Destiny 2), Jade Curtiss (Tales of the Abyss), Meltia Bandi (Tales of Phantasia: Narikiri Dungeon X), the three Kanonnos (Tales of the World: Radiant Mythology) and Tsukasa (.hack//SIGN). Tales of Time only reached Chapter 18 and all of them were summaries. Some of the descriptions below were not inlcuded in the 18 chapters of the summary but it was part of the main plan for the story.
All of these characters have major role in the story. The following are the characters' first role in the story:
Lloyd Irving- a friend of Beu Olivers from the old city of Iselia.
Nanaly Fletch- partner of Charlie Davis during Chapter 7- Hope.
Leon Magnus- he was known as Emilio Gilchrist in the story. A 10 year-old boy and also a friend of Ivan Rivers during his childhood days.
Harold Berselius- one of the creators of gridlock. She uses gridlock as a weapon enhancement.
Jade Curtiss- known as Jade Balfour in Tales of Time. He is one of the creators of gridlock. Jade prefers to use the gridlock as a part of fomicry, a method of replicating materials..... and probably people.
Meltia Bandi- one of the creators of gridlock and the cousin of Tsukasa. She was famously known as the person who created the "great disaster" during the timeline of Ion and Jarie. Later on, Meltia was discovered to be under controlled by Tsukasa.
Tsukasa- known as Tsukasa of the Waves. He has a different way of casting spells. He was considered as the only Wavemaster alive in the world. In the final part of Tales of Time story, Tsukasa revealed himself as the Twilight Guardian under the guidance of Bermate, the summon spirit of Light.
Kanonno- a being guiding Zero Bitfender during his missions. Kanonno splitted itself into three girls, Pasca, Earhart and Grassvalley. Each of them has a role to unlock the time paths leading to the distorted history of the world.
