Hypothetical: What if instead of journeying to the Freljord Sylas went...
... to Ionia and came across the order of shadows.
He's an outcast of his own homeland and feels that the rules of his people are ruining the lives of people. Mainly he feels that the nobility in Demacia is the sole cause of the oppression of mages and that the only way to liberate the mages of Demacia is to do away the the Demacian nobility (if I'm reading into this correctly).
SPOILERS FOR THE SHACKLES OF BELIEF
So he winds up traveling into the Freljord to seek out a massive power that he (senses?) and ends up teaming up with the winters claw after the shaman lady lies to Vrynna and says that she's seen Sylas in a vision or something and so he's important. Sylas ends up coming up with the idea of raiding Demaica with the assistance of the Winter's claw.
So now let's say that instead of sensing immense magical power from the Freljord he sensed it in Ionia instead. This then leads him to Zed's order.
so what happens in this scenario?
my theory is that in this hypothetical situation 1 of 2 things happens
1- Sylas' story ends up convincing Zed to train him in the shadow magics and he basically becomes a shadow assassin mage.
2-He tries to yeet Zed's powers with his chains and either Zed kills him, or Sylas worms his way out.
What do you all think? Theoretically of course
