Oneiros, Dragon of Dreams

Here is the visualization of Oneiros (pronounced "OH-nee-ros", from the Greek word for "dream") is a dragon created by Morpheus from the dreams of many men, including Wesley the Wizard.

Oneiros represents the power of the human imagination, and how you can do anything if you can dream it. Oneiros was created to counterbalance and replace the corrupted Baphomet, while also being a spirit who is himself incorruptible. He is pure blue due to the strong amount of Aura both related to his birth and from his link to the Spirit World. Blue is already a rare color for a dragon, so his existence alone is a miracle. 

He breathes blue fire and is growing at a rate fifteen times faster than the average for dragons. Himself being a rare wyrm, he is expected to become the strongest dragon ever born.
