Forgive and Forget Storms

This phenomena is caused by the effect of shards of certain nature or going through a particular mood, and is more likely to hurt some people in grief than other.
There was a time when it could happen anywhere, at any time, all over this world, and those who were affected by it wouldn't be able to do anything about it. Things are different now, but it still happens in other worlds, and we occasionally get clients by it's cause.

Why does it happen

Sometimes, when grief is to big a person is prone to lose the memory and connection to what they have lost. In contact with certain shards, they can trigger the Forgive and Forget process, and they usually affect only them.
In other worlds this is not a common event, since it isn't likely that all circumstances converge to make it possible.
Is different here, where shards are the fuel, matter and many of the living beings. They are always mixing to create all kinds of meteorological and magical phenomena. It was to be expected that the Forgive and Forget inducing shards would find each other, and interact with shards and ghosts that either trigger the process or make it worse, causing it to affect people who doesn't want to left their loss behind.

The Forgive and Forget phenomena

Is one of the rarest manifestations of shards, because it works as a magic spell would instead of taking a physical shape, but the shards aren't consumed in the process.
Those affected by it, lose their connection to what one of more things they have lost. The unrecoverable t's still there, in the the unrecoverable left in their life, but they can't remember and more important: they can't feel it.
Desperate people believe that that would be better, but they don't understand: the pain doesn't disappear, the unfulfilled need don't disappear. The sorrow is even worst when one doesn't know where it comes from. It becomes a wound that nobody can't treat because nobody knows where it is, and it can consume a person in a way that no lost would.
The memory alterations vary according to the affected person, the nature of the loss, how the magic is triggered, and why. It can be as definitive as not knowing that the unrecoverable ever existed or it can be something trickier and easier to hide, like not remembering why it was important. Sometimes, what's lost is just the emotion: they know it happened and that it hurt when they lost it, they may even know that it's the reason for their misery, but they can't reconnect with the good feelings they miss.
In other world's, tt's an irreparable damage that occurs naturally, when the wrong sorrow mixes with the wrong shards. Those able to embrace the loss or to use the shards of what they lost to build experience or even hope, are immune to those manifestations.
How often it can happen in a world depends on the relation it's people have with the Shards. The less prepared they are to process loss and use their past to build their future, the more likely is that fragments of lost things end up pullulating everywhere, and that some of them are the ones that can cause a Forgive and Forget event.
More often than not, it's a less powerful variant, that can be repaired with a lot of time and hard work. Meanwhile, many of the people affected by the full phenomena end up here—some for the second time—and get the opportunity to fix it.

The storms

"Yesterday", 4 centuries ago ago, in this world was common that the outsiders were victims of this event.
Some actually sought the chance, and many others triggered it unknowingly. But most of them got caught by the storms, even when they were trying to cling to their pain or to the hope to fight fate. There was no way to know if a place held this threat, or if the dormant shards would turn into a black hole able to eat only the love for what was lost. Even if there had been a way to detect those areas, not many of the visitors knew much about this world, and who would warn them about the danger?
Now there are plenty studies about the subject, and signs in every area that should be avoided by all travelers, and the ones that are only dangerous to those who are hopeless and desperate to stop the pain. There is no risk out of the forest, and the all its effects go away when the day restarts, just like every other irreparable damage does; as long as you aren't under a contract, you are safe.
Is terrifying and we don't fully understand it yet, but we have it under control.

The erasure

There are plenty of myths about related events that could have happened in the past, and how some of them may have something to do with the current state of this world. It's told that granters had the ability to trigger the Forgive and Forget curse, or even the storms, just like they can use shards as fuel for other magic spells, and they would use it as punishment for those who annoyed them. Cruel granters would summon storms in worlds they didn't like, or use them as barrier to keep humans away from them.
All those stories are fun to hear—some have interesting details, others are just hilarious for how little sense they make—, but the most notable pertains to the future.
It's a bit of an apocalyptic story, I suppose.
Some say we are heading there because of the restrictions the boss has imposed to keep the dangerous shards rooming free in the "forest" instead of either using or destroying them as soon as they are born. Others talk about it as if it has always been unavoidable.
One day, those dangerous shards will converge and cause a colossal storm that will cover all the premises, even—specially— the areas that we consider safe, and will wipe all memory of the Last Time Company and what we know of this world.
They think it has happened before, with what existed here before, and that it's unstoppable; that a granter can trigger it earlier, or even delay it, but no more than that.
Go and try to tell them that there is no evidence of any previous erasure, they will tell you that that's part of the storm. That physical evidences would be affected too because of some of the shards involved... or something like that. It gets more complicated and makes less sense each time they tell the story.
Don't worry, even if some of that is true, I bet the reset would fix it... We can only hope, right?
However, other worlds are safe. According to the experts, as they like to call themselves, this kind of magic requires so much energy and is so unstable, that can only happen here, where Shards always find a way to exist in harmony... Or in some sort of balance, at least.

Localization

While the Forgive and Forget effect can't occur in any world as long as there are any amount of unused shards, it only affects those who are desperate enough to get rid of their sorrow. It usually requires some sort of trigger too.
The storms only occur in this world, and the Granter has made sure to keep them in the "forest". Technically they could form anywhere in that area, given the right circumstances, but the scholars have detected some regions where they show up in every iteration of the day. There are warnings in every path that leads to them.

Manifestation of the storms

Once in a while, there is an unsettling environment about it; people in the area feel an indescribable "bad feeling", irrational fear, a sudden desire to cry, or simply nostalgia that may or may not be related to their deepest regrets.
It can also concur with negative environment manifestations, like storms, terrifying endless nights, labyrinths or emotional fields, but those aren't manifestations of the forgive and forget inducing shards.
More often than not, there is no warning for the danger, not until it's too late and what was left of your lost treasure is gone too.

Manifestation of the Forgive and Forget effects

The worst part is that we wouldn't know if it happened. That's part of the reason why is so easy to believe in related conspiracy theories, you know? Because the whole point if that we wouldn't know something, and there is so many things we don't know. Almost everything about how the world—any world—works, but also a lot of stuff about our pasts. Even the history of the company is secret to almost everyone.
Every time we can't remember something we know we have learnt and even more when we know something we don't remember learning, there is the urge to believe in something that explains it. Something less terrifying that poor brain performance. So, why not this?
There is no other manifestations for this kind of curse. Only the memory loss, that may or may not cause us to feel like or knowledge doesn't fit with the real world or what we should know about it.
We know that big bad Erasure has taken place, because we do remember our past. But any other kind... I'm just saying: next time you feel like questioning something, or someone's behavior, keep in mind that maybe they are perfectly fine and what doesn't make sense is your idea of them.
