Lore past and present

From floor 80 and up all players without exception had to take part in the wars, not battles fullscale wars.

This was done so that only those that desperately wanted to leave Sword Art Online could do so, while everyone else either died or was so mentally broken that the other players had no choice but to either kill them or let them die.

This is when the gods that were watching the events inside Aincrad fully interfered, now by the rules of Aincrad they couldn't just enter the game so they did the next best thing, they fully reactivated all of the games defense systems.

This means that everything that kept the players from killing each other regained the majority of their power.

Plus the reawakening of the programs that kept the players from going insane.

This is the reason why all of the players aren't a bunch of xenophobes worried about being attacked by everyone they meet.

So on Floor number 80 all of the players gathered and had a massive first, it was here that both the floor guardians and the gods agreed, they would do all they could to ensure that the players survived the game and whatever dangers they might find.

This is the reason why the floor guardians are with the players inside the fortress.

The Gods knew that they couldn't directly interfere, so they altered some of Aincrads rules.

This caused all of the Human N.P.C's to begin a massive migration through the floors that had their Main Bosses already beaten, allowing the players to get equipment alt easier as well as being able to do more missions because they were needed.

During this great feast, the line between the gods and the player's world blurred allowing every player that had died to be present and all of the gods to stand next to the players that were still alive.

This would later be considered a ritual so sacred by the people in Goblin Slayers world that, that those that found out about it didn't know if they should confess about unintentionally joining their voices to what would later be called the choir.

The choir will one day be considered something akin to an extremely high-level spell that only those connected to the chatroom can do, as it allows every layer and tho granted access to the chatroom by the players or those that were given access and later granted access to someone else can perform

The only thing comparable to it is the union that the elves can do because every player and everyone granted access can feel what everyone else feels.

They can see the past of everyone in the feast or somewhere else, and meet the souls of those that have already died.

During this time the gods that took notice of the players and Aincrad are able to stand next to the players and offer comfort to them.

The spell is worthless for offense or defense, as its only purpose is so everyone can remember their past lives and give thanks to those that died along the way, as well as give those that haven't been born their blessings.

During this time everyone sings if they want, drink or eat if they want to, or simply lets out all of their emotions without restraint.

After this event, all of the players began a massive campaign of defeating monsters and acquiring crystals- items- potions and everything they could get their hands on.

Unfortunately, this means that they had a bunch of things that they couldn't use because they can't use magic and a lot of the things they got were magical.

All of these useless items are in something called the Vault inside the Fortress that the players are living in.

Now from floor 80 and up the wars that were fought only became more and more insane but thanks to the changes that the gods made, the defeated floor bosses and field bosses could be summoned to help the players.

As to how bad they got think Warhammer 40k, with the chaos gods either at the point of winning or have already won.

It's a wonder that anyone even survived, this is the reason why some of the players are so strong that they can kill gods because they gained items or became strong enough to do so.

The majority of the players, however, were either just regular soldiers that fight against the weaker opponents so that those strong enough could deal with the strongest monsters or helped acquire whatever the other players needed.

That meant going back down to do missions and regain said items.

This is the reason why the payers are so exhausted ad have just kept to themselves up until now, they were just tired of fighting and that hat did only did so to gather information or keep their minds off their current situation.

As to what happened to the Human N.P.C's they died alongside Aincrad, some did survive but they're mostly automatons without souls.

Why the monster survived is because of the deal with the floor bosses, the payers were the ones that mattered not the N.P.C's so all of the ones that survived were the ones that could create crystals or whatever the players needed, as for the monsters.

These were the first wave that began to attack the recently opened floors, to help weaken the floor's defenses

This is why a lot of the monsters survived and why a lot of them didn't, the gods didn't allow the truly evil ones to exist after the game was destroyed.
