Jarylo seems like he would be very problematic to the Vex, but if one of his few limits or weakness are exploitable, the Vex may have a slim chance of victory. Shai can certainly limit the number of forces the Vex could throw at her at a time, but she's sure to be more vulnerable than Jarylo and her weapons won't save her from a proper, overwhelming assault Liu Zida seems like he could keep the Vex on their toes for awhile, but despite his ability to discern tactics the Vex are infinitely adaptable and would eventually find away to take him out before he could find a way to counter them or escape Facing all three together would certainly be a challenge to the Vex

Interesting, very. I'd love to see a fight between them. I didn't detail what units these three have control over. Just the big three. Tho how would the vex react to all timelines now being a single timeline? And how would they react to shai"s power ti brung back the dead?

Well as soon as the timelines are cut down to just one the Vex will have a lot less numbers (although still an absurd amount) but time will automatically begin diverging into multiple possibilities again and they will rebuild. They would also obviously decide to eliminate whatever entity caused that setback If they observed her reviving the dead they would determine her to be a primary target and attack her first so she can't bring back whatever else they kill

I see, how would they confront jarylo in his realm? Every step he would know about. And if they don't see her do so? Hmmmm, well can vex create different timelines?

Well there's gotta be a way into his realm, and there's a possibility that he can't stop or counter every attempt they make on invading. So it comes down to what exactly it takes to kill him and what numbers he can fight against at once Well I mean in this scenario the Vex and the 3 beings would know who they're fighting, so right now it may be better to just assume that the Vex can learn of her abilities somehow (which they probably can). The Vex can't make timelines, but they most certainly can follow divergences and spread into other timelines as they come to be
