The plane of Memory is a shadowy dimension populated with historical imagery made manifest. The plane seethes with psychic impressions, where mortal and immortal replicas and scenes lost to time recur endlessly. Their permutations are limited by recollection and their replication is often imperfect, influenced by the perception of collective memory.
It was from the plane of Memory that Lupus attempted to summon and resurrect his memory of the dead Selene in 844 AF, an act counter to the fundamental strictures of reality. The act tapped into the horrors of the rise of Bal'met, the aggregate fear releasing memory Dala'myrr and other nightmarish creatures into the Prime Material Plane.
It was also from this place that the Conclave recalled the champions of the second Reckoning to create the forays in 906 AF.
Memory was the staging ground for Pazuzu's war upon the Prime in 922 AF, his refuge from pantheonic retribution, and ultimately his grave after his failed final stand against them. Finally it was from this plane that the Bloodsworn Gods uprooted a memory of Shallam, concretising it into primal reality in last ditch exchange with the foundations of Targossas which the plane had claimed as its own in 928 AF.
The icon statuette talisman is an artefact related to this plane.
