Okay you may watch movies like "Dragon Heart", "Dungeons and Dragons" (Sorry if I spelt "dungeons" wrong). You may think, "wow dragons were real once", but I am sorry the closes thing you will get to a dragon, is the Kamoto Dragon, which is only a preditor that can eat it's victums in a fast rate.
Dragons are spiritual creature, some may call them guides, some may say they are evil spirits, I say they are very wise and creatures you may gain advice from.
Dragons throughout mythology has been called many things, killers, the wise, the terror bringers, the fortune bringer..ect.
But I believe they are the wisdom teachers. The advice givers.
( I know fairly well many people will argue this statement, but it's my opinion, feel free to place yours if you wish, but respect mine).
