Ok ok minions, do not panic. This is not another expansion announcement! The SoE is something else entirely, it is a lorebook that the great Liberty is currently working on, the person you have to thank for the amazing and disturbing lore of cults :)
It will take the form of an in-universe book, written by somebody that most players already know (but I can't reveal who they are, it'd be a big spoiler, sorry!). It will discuss various aspects of the world of Eyal, its history, its inhabitants, the way the universe works, the nature of magic, souls, Nature, ... And lots of stuff from outside of Eyal too, from the local star system to things much further away...
Here is a little quote from it, where the writer discusses horrors:
When designing the Sher'Tul, Amakthel had numerous failed experiments. Rather than dispose of his misshapen creations, he ignored them and left them to their own devices. They multiplied and spread through Eyal's underground. However, Amakthel wasn't wholly responsible for this plague. The Sher'Tul also created many bio-weapons during their civil war. They engaged in the same sin as their father and reshaped life for their own ends. They degenerated their own brethren, mutating them beyond recognition. To their credit, they tried to clean up the remnants of their war, but some horrors escaped their notice. There are also horrors which came to Eyal from space. All three of these groups are collectively referred to as eldritch horrors. I have catalogued various types of eldritch horrors below.
Obviously, I will not give any release date for that one, but I'm sure lots of you will be eager for it! I'm not yet sure the format of it either; probably some kind of ebook maybe also distributed on external ebook platforms, or who knows if there is demand, maybe as a physical book too. Please give us your opinions on that!
