this isn’t what happened at all. you might want to replay gw nightfall. especially the last two missions where the gods made it clear that they are leaving (and why)
this isn’t some sort of lore they made up for gw2 it is what was around since nightfall
In neither Gate of Madness nor Abbadon’s Gate do the gods state why they were leaving and that they were. In fact, the avatars state that the gods are present in human nature and that these characteristics were the gift to he player. They then give Kormir the gift of ascending to godhood.
The gods were not a physical force in Guild Wars 1 at all. Their avatars were. They left Tyria in 0 AE after creating and splitting the Bloodstones to contain magic. Since you have a lacking knowledge on the lore of Guild Wars, might I suggest reading the official Wiki? It’s a great source for newcovers to the world of Tyria.
Abbadon gave magic to man. War erupted (not the first one. That I was wrong about). The human gods, residing in Orr, heard Doric’s pleas and created the stone to draw man’s magic back and separate it from being pooled into single sources. Abbadon became enraged and fought, with the Margonites, against the Six. He lost, was cast down, and the human gods resolved to leave Tyria so that man could live free of magic.
Except that that is entirely unrelated. See, the human gods ‘left’ twice. Once, as you were going on about, after the Bloodstone/Abbadon fiasco, and a second time as Dragan was saying at the end of Nightfall when they stopped leading the humans by the hand. Now, pretty much everything you said is true, but it doesn’t matter. That fiasco happened more than a thousand years before the events of Gw1, in which the whole Grenth vs Dwayna was still going on. Because of that, we can deduce that they must be referring to the second ‘leaving’ of the gods. Dagan is mostly corrrect. I would recommend you read the Gw1 and Gw2 wikis, as they are a good source of what lore we have.
Gate of Madness
Lyssa’s Muse: “This is your world, now. This is your decision. You must make the choice that only a mortal could make.”
Think that about sums it up.
