Send me "Switcheroo!" and I'll redesign your muse as if they were from my muse's universe
Well, suddenly I wish I was RPing an FE6-7 character, because Seraphim would fit pretty well as a sentient War Dragon.
Working with Archanea, tho', I'm going with a Mage Dragon from Pyrathi. Somehow finding themself exiled, Seraphim wandered the continent.
Somewhere down the line, he drifted to Khadein after hearing that the city of magic had been founded by one of the Divine Dragon tribe. Deciding to stay, even after learning that Gotoh, the aforementioned Divine Dragon, had disappeared years previous, Seraphim started learning Thunder Magic, aided by his species' natural inclination toward thaumaturgy, and even began to form friendships with the teachers and other students there.
Such peace was not to last, however, and not much later Gharnef began his coup. Though Seraphim and many others tried to fight back, eventually all resistance was overrun. Seraphim was forced to flee, bringing with him only a weak and unstable tome of his own devising.
Seraphim again wandered the continent for a few years. After the events that transpired in Khadein and the deaths of many of his friends, he became closed off and wary, not helped at all by the natural lack of emotion held by the Mage Dragon tribe. He had as little contact with humans as possible, though he still welcomed the company of the few manaketes he met in his travels.
When Gharnef had been slain and Khadein freed by the Archanean League, Seraphim did not return, instead choosing to travel to what remained of Dolhr after the War of Shadows.
Two years later, this was where he encountered the Altean Army on their way to the Dragon's Altar. Resolving to join them, Seraphim used his draconic powers and magic to aid them in their effort to prevent Medeus from breaking the seal on the Earth Dragons, which would bring wrack and ruin upon the world.
After Medeus had been slain this third and final time, Seraphim traveled to Altea to finish his education in magic under the tutelage of the newly-appointed Archsage: Gotoh.
