Let me explain: there are dragons, and then there are drakons.
Drakons are several millennia older than dragons, andmuch larger. They look like giant serpents. Most don't have wings. Most don't breathe fire (though some do). All are poisonous. All are immensely strong, with scales harder than titanium. Their eyes can paralyze you; not the turn-you~to-stone Medusa-type paralysis, buttheoh~my~gods-that~big~snake~is~going~to~eat~me type of paralysis, which is just as bad.
