No worldsoul memories on map

[FatGandalf]

How often are these active? Haven´t had one on my map for 2 days. Have 4 radiant echos in my bag. But 0 worldsoul memories on my map.

[Armael]

They are only in zones where the memory is active. On my server that is Hallowfall and Azj-kahet today.

[Savian]

They are only active in ONE zone per day and they rotate in a fixed pattern: Ilse of Dorn > Ringing Deeps > Hallowfall > Azj'kahet.
They are always in the same 2 spots in the zone, will always be same theme and spawn the same mobs and set of rares. For extra visibility there are those Azerite orbs flying in the sky that give you Crystals and Crests if you fly through them.
