Mikkel is a character only mentioned in the graphic novel, The Serpent's Heir.
King Mikkel is only mentioned by his son to the Dragon Riders and company, when they arrive on Nepenthe to investigate the quickening island tremors. There is no indication of what has happened to the older Mikkel, or if he is still alive. There is no indication how his son, Mik, assumed the throne.
Both "Mikkel" and "Mik" had the same exact same name and titles. It is unclear if he was "the First" and Mik "the Second", or if the title Mikkel the Munificent is applied to a much longer line of succession. Mik does not appear saddened in the least when mentioning his father, suggesting they may not have been that close.
