Sequiro: MAJOR SPOILERS DOGEDDIE PLEASE DO NOT READ MAJOR SPOILERS I don't like talking about this stuff in a topic of someone that probably hasn't seen the storyline.
Not exactly, you have to play through Defiance to see the actual trap. The trap isn't BO2, BO2 is the result of the trap..or basically the attempts to see his entire plan fully come to fruition By keeping Raziel out of the Reaver for a while longer it allowed Raziel to resurrect Janos Audron, which is what the trap is, that's what he wanted to have happen. They needed an actual Ancient Vampire blood to power/use for The Device Which the Sarafan Lord is looking to use to eradicate all Vampires and Humans from the face of Nosgoth leaving the land for his people alone to come back from the Demon realm to inhabit.
This is the main reason why playing Defiance first I believe is so important. I mean it's bad enough Vorador is there, and more vampries, but then Janos as well. both are supposed to be dead. The Sarafan Lord himself and the Hylden.. where did they come from? Whats going on?
Defiance sets up Blood Omen 2 better by seeding these answers in ahead of time. So now if a person play Defiance then plays blood omen 2.. he'll be OH that's what happened to Janos after the Hylden Lord kicked Raziels ass and flew away and it immediately explains who these Hylden are and more specifically who the Sarafan Lord actual is. The same guy that's been involved in everything.
It just makes it all less confusing.
XYCat: Blood Omen 2 is the result of changing the history that came with soul reaver 2 and Defiance is supposed to be the final closure.
Avogadro6: SR1-2 end with a huge cliffanger, Defiance was so much better in that regard and brought some closure, but the story is still very much open at this point.
I'm still expecting one or two final games to close the saga.
XYCat: What's open about it? Kain defeats the tentacle god that's been causing all the trouble around and finally becomes the guardian of ballance that he was supposed to be from all the way back in blood omen.
A) EG isn't dead.
B) Kain is cured of his madness, yes. HE has a purified Reaver, yes. BUT:
-he's Elder Kain, with Younger Kain existing simultaneously, still mad.
-the Pillars are stil broken, anfd neither Kain knows how to restore them.
-The question of the Hylden witch (who looks like a vamp/hylden hybrid) is open.
-The only person who MAY know how to fix the pillars (Janos) is under hylden control, doomed to be hurled into the Demon dimension (aka, where the Hylden came from) 200 years after Defiance, at the end of BO2.
the story won't be resolved until the Pillars are restored, with vampire guardians. we're nowhere close to that yet.
