Thoughts on where things can go.(Spoilers involved)

[Kaecilius]

We are Azem's shard. And it's entirely possible that Azem created the device possibly as their answer to the Final Days. Or they could have had prescience about either the Final Days or future events as was hinted in the Pandaemonium storyline when they told Themis a falling star would appear before him. And then we fell on him.

We are the current iteration in the Source, but it's entirely possible Azem lived as someone else before, then died and they were eventually reborn as us. We also know that people from the Reflections can be targets for awakening as Ascians/Ancients, such as Gaia being the reincarnation of Loghrif.
