Soul Reaver 2 - Raziel emerges in Future

the future was the most annoying part in the game

I don't count it either but BO2 only exists after SR2 not Defiance.

Technically Moebius didn't kill Vorador, he just rallied a mass Vampire genocide, Vorador was caught, end O story.

I tried to replay this game a few days ago but im so used to being able to save whenever that i just couldn't stand to play.

Question,(i know it might sound dumb but i never played SR2) in this video,Raziel emerged in the timeline of Soul Reaver 1?

Prior to SR1, actually. Considering the point of Kain's choice at the pillars at the end of BO1 to be T, SR1 takes place in at least T+1000 years. The exact time is not given, but it's at least 1000 years after, as Raziel specifically notes that Kain had ruled for 'a millenia'. It's been fairly accepted that the jumps in SR2 are in 500 year increments - that is to say, this is 500 years ahead of where he started, and the jump to the past later is 500 years prior to where he started originally.

nice thx man

Normally, they can't. They are starting to be able to (and the Hylden are starting to be able to extend their influence out of the demon realm) due to the weakening of the pillars and their subsequent destruction - this is what the ultimate result of Kain's choice was.

Okay ,final question: those priests in the cathedral are able to summon the red demons.
Why and how do they do that?

In Blood Omen 1, the guardian of the Pillar of Dimension, Azimuth, was a powerful yet sadistic sorceress who used her power to both look into other plains of existence and open portals to them, to bring demons and other horrid creatures into Avernus. The Cenobites, her servants and acolytes, were able to do the same thing to an extent. Besides, the Avernus Cathedral was one of the most hunted places in Nosgoth... and it was deeply connected with the Demonic Realm. D.R.
