Please note that I don't own any of the Fire Emblem characters, countries, or plots, as much as I'd like to. Anyway, here goes.
Naesala. That name, the name of the Laguz Crow King, was not one to say idly. The name of the one who had slaughtered sea faring Beorc humans out of spite and greed was not one to be taken lightly. Just as the king before him, and the king before him, Naesala had fought his way up through the ranks of Laguz royalty, until he alone remained at the top. The blue haired crow king's power was said to rival that of the Herons; at least, when they were still alive.
Naesala. It was the very name that had made the Beorc humans slam their shutters and lock their doors, the name that had long since plagued the other Laguz tribes with fear of the power that rivaled their own kings'. Naesala was feared even in his own court. Perhaps especially there; those close to him had to make sure they were in his favor. Not many were however, since Naesala didn't judge the Laguz nobles by their ability to compliment him on his accomplishments, but by their ability to fight. Thus, most noble children were raised to join the military if Naesala desired. Those who failed at this were weeded out.
Naesala. The name of the one who had earned the once respected Crows the title 'pirates'. Now the tribe of Laguz preyed on human ships that came within the range of their island territory. They never strayed beyond it far however, at least, none of the ordinary Crows did. Naesala himself had no fear of the Laguz Hawk or Dragon kings. Not even the king of the beasts' roar could shake him. Naesala loved this kind of power, and would do almost anything to keep it, even if that ment joining sides with some of the humans in their war of the North. If he played his cards right, it would benefit his tribe more than the humans who won.
In spite of his constant observations and thought, Naesala might find a small snag that would likely unravel his entire being, were it not taken care of. This snag took the form of a fledgling of his own tribe, though neither of them knew it yet.
