Haha, it's all good! I'm glad you replied. I don't use/am not fond of discord; I prefer old-school forums or bulletin boards for accessibility of information on the clearnet, but it's you decision to make at the end of the day =)
For Dojo and light, any thoughts on luminescence? Not to be confused with luminance and illuminance, luminescence describes many processes by which light is emitted. It can be a biological trait in many organisms (though usually not in turtles irl, haha), and the word itself is an abstract uncountable noun like the other three. My other picks would be radiance and glow, the former fitting the cozy vibe of the game and the latter being the namesake of the verdant accessory.
Thank you for clarifying on Sanguine Signet! This game is such a treat to play.
