Chronicles of Elyria is an upcoming MMORPG[2][3][4] also commonly referred to as a MEOW (Multiplayer Evolving Online World), developed by Soulbound Studios for Microsoft Windows. Development of the game began in 2000 (see Development section below). Production started in 2016 with the majority of financing coming in the way of a large crowdfunding campaign. However, in January 2018 the company announced[10] they were no longer using SpatialOS due to Improbable announcing [11] that SpatialOS had deprecated support for JavaScript SDK among other issues.

As such they have instead incorporated piecemeal solutions such as Docker Swarm and RabbitMQ for server technology onto their own Soulborn Engine. Prologue: The Awakening, which will be able to be played both as a single-player and multiplayer game set in the same universe as Chronicles of Elyria (CoE), is also being developed. It will be free to download and play as a solo experience.
