Since the beginning of time, he was known as Muninn, Keeper of Memory. For all of Midgard's existence, Muninn has flown the skies and recorded all that the Midgardians accomplished, and every night he would report these things to Odin's right ear. This was all Muninn ever wanted to be. He was content and happy.
Only now, as Odin prepares to unleash the next step in Midgard's evolution, his purpose and form are about to change for good. He is sent, with Huninn, to the Dwarven world, where his form would be changed from immortal raven to cold, unfeeling metal, and he will henceforth be known as Mantis, Giver of Knowledge.
At his side, once Huninn, stands his friend Gorbon, and the two set sail through the cold, unforgiving void of space, to Midgard. There, they will find and train Midgard's first evolved and help them save the world.
Only then may Mantis ever return to his previous form as Muninn, Odin's right-hand bird.
