Now that the bloodstone powering the Door of Komalie that prevents the Titans from entering Tyria is shattered, it's likely that the Titans will come back from the Foundry of Failed Creations. From what I understand the Foundry is a special location located in the Domain of Anguish within the Really of Torment that Abbadon was imprisoned in. It connects to the underworld which is connected to the underworld via the bone pits, both being located within the mists.
Now I'm just taking a guess that the Titans must already have some sort of influence on a dragon, and the dragon I'm looking at in this scenario is Primordus. It's likely that the Titans that gave the Flame Legion their powers are coming back with a vengeance. In relation to Jormag, it's just one other big massive ball level of a problem to think about just to realize how bad things are going to become in Tyria.
