"Now, let's see what this is capable of. UP!!"
The hellbeast spreads its massive metallic wings and springs foreward, before beating the air under it's heavy wings and swooping into the air.
They fly fast, quickly gaining altitude. and the great black leviathan soaring the skies above gets closer by the minute. Youngbull notices that the beast doesn't seem to be affected by the heights that had earlier knocked him out cold, sending him falling towards the ground.
Soon they penetrate the cloud layer and sees for the first time the great leviathan in front of them, it's length going for miles on miles. and golden yellow eyes stares at them from a head more then a hundred yards long, covered in heavy draconic scales. the leviathan itself looking more like a serpent of sorts, like a Naga with wings. (for those playing Warcraft 3/WoW this should be sufficient) The leviathan fixes it's gaze upon the newcomers and studies them patiently.
"So, this is what i couldn't reach earlier?"
Youngbull looks at the leviathan with awe, trying to figure out it's nature.
"No matter, it will soon obey me. Hellbeast, foreward!"
The leviathan's pupil expands in wonder as Youngbull commands the hellbeast to fly up to it, close enough for him to get onto it...
