What is stellaris stellar devourer?

As an AI language model, I do not have access to up-to-date news and cannot provide insights beyond what is available online. However, Stellaris is a popular 4X strategy game developed by Paradox Development Studio and published by Paradox Interactive, released in 2016. It is set in a vast galaxy and players take on the role of a spacefaring civilization, exploring, trading and fighting with other empires. One of the threats in the game are the Stellar Devourers, which are described as massive creatures that roam the galaxy, devouring stars and sometimes even entire solar systems. They are known to attack fleets and cause catastrophic damage if their path is not avoided. In the game, players can encounter these creatures and either attempt to slay them or make a deal with them.
