Dragons

Very little is known about dragons, other than that they exist. The potion seller makes the claim that his potions would 'kill a dragon'. It can be inferred that the potion seller says this as a brag, which implies that dragons are powerful, more so than a man. However dragons are also not the strongest creatures, as the Potion Seller's Potions are meant for only the strongest but the potions would put down a dragon.
