James Lake Sr. (Misry6)

James Lake Sr, real name Mordrax, is a mentioned character in Trollhunters and will appear in the upcoming fanfic Fall of the Arcane Order: Before the Tales and the Misry6 rewrite of Trollhunters: Rise of the Titans. He is the first wizard, the ex-husband of Barbara Lake, and the biological father of Jim Lake Jr.

History
James Lake was the first of the wizards, born as Mordrax in Ancient Greece, 3,060 years before Trollhunters. He was one of the ones who knew Bellroc, Skrael, and Nari before the latter three were christened the "Arcane Order" by the god Hades. At some point in life, Mordrax encountered Nimue, who expanded his lifespan, gave him magic, and declared him "the first of [his] bloodline". It was around this time when he met his raven familiar, Brimrod. When the Arcane Order (sans Nari) were willingly manipulated and corrupted by an entity from another dimension, Mordrax was among the first to revolt against them. Eventually, Mordrax came to live in Camelot for 100 years and was an associate with Merlin for quite some time. He was also against King Arthur slaughtering the trolls in Dwoza.

Years passed, and during the modern-day, Mordrax went by the name James Lake Sr., met Barbara, and the two married and had a son, Jim Lake Jr. However, he never told her nor her son about his encounters with the supernatural world, nor about his time prior to coming to Arcadia, as he wanted her away from his other life to protect her. Nevertheless, he loved his son and his wife, as he bought his son a bike kit on Jim's fifth birthday. That night, Nimue froze time and directly appeared to James, telling him that, despite Kronos and the Titans' exile to Tartarus, his forces are still at large and massacring the multiverse. When James was reluctant because he wanted his family unharmed, Nimue said that "the only way to save [his] family, is to leave them behind", and convinced him not to write a note nor make any phone call about it.

With that, James left without a trace, and the following night, had his friend, Kirk Clover, make up a story to Barbara that he ditched her and went off to become a ski-bum with his girlfriend at Vermont (which Toby overheard), to continue to keep her and Jim in the dark about what was truly going on in James' life.
