The two main characters are surely the little wizard and the dragon. The little wizard might be a young and inexperienced spell - caster, full of curiosity and a thirst for adventure. The dragon could be a majestic and fearsome being, perhaps with unique powers like breathing fire or flying at great speeds. There could also be other characters in the periphery, such as the wizard's mentor who may have given him some initial guidance before he set off on his adventures with the dragon, or local villagers in the magical land who are either in awe of or afraid of the dragon and the wizard's presence.
