Thunderwing was a male dragon who lived during the Age of Fire in Dragon Tower. He had a strange scale color pattern: watery blue covered with tiny white flecks.
He had a fine sense of humor for dragons, and the Copper nick-named him "the philosopher-king", but such name brought further humor on him by other dragons.
He was described as old, a veteran of the Dragon-riders Wars, known to have personally sunk 3 ships of the elves.
During the wars, he was crippled and joined the grounded dragons of Dragon Tower.
He was took part at the Second Battle of Hypat: he was also the one who came with the right idea to ferry the barbarian reinforcements by dragons.
Being a fighting dragon in the ranks of Dragon-riders, he was probably castrated.
