Niko's Memory has restrictions on where or how it can drop.
Found in T14+ Maps.
Using this item on a completed Map on the Atlas of Worlds will cause several connected maps to activate a quest chain for the named Master. Speaking to the NPC will provide a dialogue snippet that does not change, as well as an option to open the marked Map. This map can be modified with currency, fossils, and Delirium orbs, and can become corrupted. The map does not use the player's Atlas Passive Skill Tree as it is considered opened by an NPC, similar to Kirac Missions. It cannot be modified with fragments. Each successive map opened will have modifiers that increase in difficulty.

While traversing the far reaches of the Atlas, I came upon vast chasms that shone with a ruddy light. Strange creatures emerged; bizarre monstrosities, heh, emblazoned in unearthly fire. The flames smelt foul, as if these creatures had somehow managed to ignite pure sulphite and were wreathed in it. They began to chitter at me in discordant tones, haunting the very marrow of my bones. Reminded me of my days in the Templar asylum. I knew I had to run...
The area will appear as if it is Scourged (in the Nightmare Realm), and Abysses appear red and spawn Beyond monsters when the player approaches the fissure. Beyond monsters spawned from abysses can drop Abyss Jewels. Other sources of Abyss Jewels (e.g. Abyss Rewards from Legion or Blight) also have a chance to become corrupted.

"of Demonic Onslaught"
of Demonic Onslaughtof Demonic Onslaught Suffix Areas are Breached Areas contain additional Large Breach Hands Breach Bosses have a chance to drop a Breachstone
Not too long ago, I came upon the telltale purple light that usually precedes a bit of demonic terror. Ol' Niko knew what to do, right? Just hide and wait it out. Thing is, it didn't fade like usual. The glow remained, and the demons crept about freely, more and more of them as the minutes wore on. Thought I was a goner for sure. Thankfully, I had some sulphite with me. Burned so brightly that a few of the fiends began to recoil, then catalysed an explosion. I was coated in soot and demon-giblets, running for my life. Wouldn't go back there, not even if you paid me. Voltaxic sulphite has saved my life many times over. There's a reason I hold the stuff in such high regard, heh.
The area will appear as if it is a Breachstone area (without the ground effect) and contain several Large Clasped Hands.

"of Grasping Hands"
of Grasping Handsof Grasping Hands Suffix Areas contain many additional Breaches Breaches open and close faster
At the behest of Kirac and his brigade, I found myself deep within the Atlas. I was minding my own business, as I usually do. And then I saw not one, but two... hands. Horrific, inhuman hands... At first, I thought it might be a mirage, but before I knew it, I was surrounded, and damn near gutted by one of them – which snapped me out of my reverie good and proper, heh. Then I realised there were hands popping up all over the place... and a deluge of demons coming for me. I had no choice but to run.
Other sources of Breach Splinters (e.g. Breach Rewards from Legion or Blight) also have a chance to upgrade into Breachstones.

Rare and Unique Monsters found in Areas are Possessed and their Minions are Touched

Rare and Unique Monsters in Area are Possessed by up to 4 Tormented Spirits and their Minions are Touched
Area contains (4/6/8) additional packs with a Rare monster
I don't often go into the Atlas, but when I do, I'm there for one thing: sulphite. Mind you, it's not the most pleasant place to be, heh, especially not when the monsters are behaving... shall we say, erratically? They seemed to be possessed by unseen forces, and were spouting all kinds of gibberish. It was very... unnerving.
Applying Delirium orbs to the map will generate more Rare monsters to kill.
Once inside the map, Rare and Unique Monsters in Area are Possessed by at least (1/2/3) Tormented Spirit(s) and Rare and Unique Monsters in Area are Possessed by up to 4 Tormented Spirits and their Minions are Touched are combined into a single modifier: Rare and Unique Monsters in Area are Possessed by (1/2/3) to 4 Tormented Spirits and their Minions are Touched
