It is official, yes, but no, it does not follow up with the Human. Here, you play 2.5 years after Adastra as a Wolf named Scipio, going to Khemia for... well, you gotta play the game ;P
This story will focus mainly on Neferu and his family/backstory.
I say "will' because the game's dev is currently on hold. The actual gameplay's 30min long.
The writers are focusing on another game that takes place during Adastra: "Interea"
