TAEL

The Great Waking - His Birth
Not much is known about Him, only that it is a shade, and an improvement of his former self, After his awakening from deep within the now awakened Erdtree, and his expelling from the main body of the tree with several other incomplete creations. Upon being dictacted, still in a shapeless, hollow self, the new Tael, it would raise it's hand and begin casting a spell - The Great Waking - which caused all the remaining souls in Caelum to resonate with his own, having everyone awaken their EGO at once. It is unclear wether this was part of Complete Tael's plan, or a deliberate act of Tael to strengthen the people of Equinox, so that they could fight for their land even with all the stars had faded from the sky.

The Learning- His Objective
Tael's objectives are by no means obscured to anyone or anything, as he is incredibly open about it. He wishes to learn about Excellion, and by proxy, about the secrets that he holds deep in his mind. He is so open about this in fact that were they to meet, he would literally just tell him to make things easier on him and not be an idiot following him, having no inhibition whatsoever. It has also been confirmed by Tael himself that he wishes to learn those secrets to fix the broken Excellion and achieve the best ending he can.

He also seems to have a passing interest on this Lucisfear person and how did they even manage to do this. He doesn't seem to irrationally fear him, but instead, thinks he may be the key for exactly what he needs.

The Beginnings - His Ideals
Tael makes his ideals clear as soon as he appears, once again having no inhibition or need for secrecy at all on his behalf. Being a man who has seen every stage of the world at every time, every second Reality in all places at once, he sees the truth about himself, and several instances where a shadowed persons influence changed history severely... Through simple deduction, he deducted that this person may aswell be Excellion. For that, he wants to know exactly what he is, or his secrets.
