It's Amazing how will this managed to communicate tone and world-building through flavorful-text and style. 

The style permeates through the Art, the Graphic Design of the book and the writing and Tone of the Text. The vibe of a dead pixel word covered in ashes.

Annwn, a land built on and inside the body of goddess who tore out her eyes finger and limbs after pulling open her own chest. It's unclear if she did it for a reason or if her limbs tried to fight her. This world building was holly communicated through flavor text. It both injects a lot of world into the game while leaving so much room to build. It's so will crafted that through simple flavor text it manages to build the idea of twice dead MMO world and an irl dimension of play while allowing to focus on it as much or as little as you wish.

My only problem is that some of the writing can be unclear about what it's pointing to or what it means, while that might leave room for interpretation it can be frustrating. It's minor but something to keep in mind.

This is a master-class in writing a lightweight TTRPG with lot of style and personality.
