I didn't do step 4 but still progressed in the questline. Any reason for that?
I have no idea how but I got INVADED by Creighton during Twin Princes boss fight!!! He killed Sirris, killed Orbeck and let me fight the boss all alone after I finally killed him. Guess what happened then...Even after I've done all Sirris quest line and killed him several times, this b**** came back from the deepest hell to haunt me! So if you intend to summon Sirris for this boss fight be carefull.
The sign didn't appear for me until I went back to Smouldering Lake and killed Horace. I actually thought that was the trigger and was surprised to not see it mentioned here.
Hellgate: London was not a roguelike at all.
You don't have to kill Pontiff Beast to progress her story. Once, you're past church of yorshka and get to the water area, beast will relocate there (and attack you tehre untill it gets killed). After triggering its "relocation" you can find sirris sign in peace and help her.
Ah, rip feelings. Anyway good storyline.
