(Mitron is NB and uses he/they pronouns.)
Mitron awoke before Eden was fully able to release him, due to the actions of Urianger/augurelt_txt - he was trying to summon Moenbryda in the Empty, and Mitrons' soul gripped to such. However, Mitron could not quite remember that he was Eden at the time. But all he wanted was Loghrif.
He eventually - with the aid of Seri - found a sickly shard of Loghrif in the form of a Vii. This Loghrif had hopped from another shard - perhaps even the Void, lingering in a shattered form, and did not remember themselves either. However, these two broken shards reunited, and remained in a fused form. Mitron is aware that the Loghrif they sustain isn't theirs, but... will protect.
However, post-Eden, Mitron remembered. And still carries this sickly Loghrif, this one who was about to become an Eater. However, they sometimes shift into Eden Minor. Often when they're weak or heavily emotional.
But now, Mitron has gained the power they lost. As Eden is freed - oddly, they need to thank Urianger for this as well. Even if he is still filled with hatred and anger.
--
When not angry and bitter, Mitron is an excited fishing fan and scientist. Currently, they spend their time in Amaurot, but still loves to wander the First to see how it's surviving.

Mitron is missing an eye, after a half-finished creation attacked him, long ago. He refuses to recreate it. It also weakens his soul sight - he has trouble recognizing souls. This has made it harder for them to find Loghrif...

Mitron, under that anger, is a very kind soul. I have descripted him before like an ocean - heavy waves of emotion. And, hey, they did cause a Flood. (And chastise themselves over having done it.)
