Lore:
Daughter to Queen hurricane of the Skyclaws. (a sub-tribe of stormwings)
Has Stormspeak (The ability to control storms, and use bolts of lightning to fly at incredibly high speeds)
When she was a dragonet, she had come across a dying stormwing dragonet. She brought them back to the Skyclaw palace. The dying dragonet survived, and was given the name Lightning.
Lightning became Thunder's best friend, and also her personal servant. He would support her through anything, and later became her mate.
Thunder would later on, after the war of sandwing succession, challenge her mother for the throne. She would kill her mother in a duel, and become queen.
