If you are referring to Judeo-Christian history, than it is likely Seraphiel. However what you are referring to as 7th level enlightenment, dark angel/prophet/chosen one, sounds more of a mix of different secular/cultic beliefs. Seraphiel is described as a brilliant towering angel as tall as the 7 heavens. He is a Commander or Chief Archangel within a class of angel known as the Seraphim, who stand in the direct presence of God. I know of no credible document that asribes Seraphiel as The Chosen One however, he is placed in charge over the Seraphs and teaches them songs for the glorification og God. His face is like the face of angels and a body like the body of eagles. He is beautiful like lightning and the light of the morning star.The Elect One or Chosen one is likely a separate entity that you are referring to. In the Book of Enoch I, Chapter 45 a Revelation is given concering The Elect One.
'On that day Mine Elect One shall sit on the throne of glory and shall try their works, and their places of rest shall be innumerable. And their souls shall grow strong within them when they see Mine Elect Ones, And those who have called upon My glorious name: 4 Then will I cause Mine Elect One to dwell among them.'
As the passages progress, in Chapter 46, Enoch on his tour of the heavens sees the Head of Days which is Father God. Immediately after Enoch sees one with the Father who is remarkably different from all those in heaven.
'With Him was another being, whose countenance had the appearance of a man, and his face was full of graciousness, like one of the holy angels. I asked the angel `who went with me [...] concerning that son of and who he was, and whence he was, and why he went with the One to Whom belongs the time before time.'
The Angel that gives Enoch the tour of heaven replies,
'This is the son of man who has righteousness, with whom dwells righteousness, and who reveals all the treasures of that which is hidden, because the Lord of the spirits has chosen him, and whose lot has the pre-eminence before the Lord of the spirits in uprightness for ever'
This is a clear indication of the Pre-Existence of Jesus Christ in heaven before his earthly birth.

ANGELIC VENERATION, WORSHIP, PRAYER AND CHANNELING IS PROHIBITED. ALL OF THE ABOVE ARE RESERVED ALONE FOR AND WITH GOD. GOD REVEALS PRIMARILY THROUGH HIS HOLY SPIRIT NOT THROUGH HIS ANGELS. MANY HAVE BEEN DECEIVED BY DEMONIC AND EVIL SPIRITS APPEARING AS ANGELS OF LIGHT, BEARING FALSE MESSAGES OF NEW AGE RELIGIONS AND PHILOSOPHIES. IF GOD WANTS TO TELL YOU SOMETHING HE WILL DO SO BY HIS SPIRIT NOT THROUGH HIS ANGELS.
