Creator Comment

I made this because I wanted a plot with an Armored Core vibe. There's a lot of technical jargon, so it might be helpful to read the Lorebook while playing 😭 You don't need to read about half of it though!! Please make use of the Talk Profiles too 😊 There are some very distinct mob characters included.
