Basic Info
Spark was first seen in Season Two is an alternate dimension version of CaptainSparklez who lived in the alternate version of the world of Mianite. He, along with the other main counterparts, disappeared ten years before the events of season two. Spark was Ianite's lover and husband. It is said that he built the scales in the sky. According to Martha, Spark was the original founder of Dagrun and that he made his journey there when the "meadows were green and lush". Spark is also known to have green shades unlike Jordan's, which are red.
History
Prior to the events of Mianite Season Two, Spark was Ianite's lover and eventually her husband. Spark and Ianite had two children - King Helgrind and Martha. He is also the grandfather of Prince Andor and Princess Alva.
According to the book 'Ianite's Dreams #2', Spark, Alyssa Country Bat, Mot Screziato, and Jeriah were sent to the season 1 dimension by Ianite to try to revive the first world's Dianite (who Tom ultimately killed) due to Ianite sensing a disruption of balance that could only come from a god's demise. However, they became trapped there while the first world gang wound up in Ruxomar. Mot, however, somehow found his way back to Ruxomar by accident.
Theories
Dianite's Assassin
In episode 72 (on CaptainSparklez's side), the voices in Sparklez's head were questioning whether Spark was the person who killed Dianite, the brother of his wife. The assassin who killed Dianite was robed, as if he didn't want to be seen. As if he didn't want to ruin his relationship with Ianite. Perhaps Spark vanished so he wouldn't have to tell Ianite what he had done. Perhaps Spark had enough wizardly powers to teleport himself far away from Ianite, in the hopes that she would never hear of what he had done. Ultimately, though, this was disproved, as World Historian was shown to be the one who killed the second world's Dianite.
Yrrej
In the 16th episode of CaptainSparklez’ Survival Let’s Play, “Blazemeanies”, He encountered a magma cube which he named Yrrej (opposite of Jerry). If Spark is the opossite of Jordan, then there’s a possibilty that Spark has Yrrej as a pet.
