Comment by Galactic Navy Officer on I Became The Game’s Biggest Villain - Chapter 4

Didn't they say the Dark Warrior was the only hidden role?

So one of two things:

The one that kills DW becomes the DW. Which some developers would do because it's hilarious.

There's one hidden role for Dark and one hidden role for Light.

I do like the detail that there was no announcement he joined the Dark Faction until someone in-game knew it for a fact. Nice storytelling.
