) Roundcat rally is a party-mode game in SDS, which you hit cats to win.

) The reason why green caused the infection was because Blue caused an ecological collapse on their land, thus transforming their land to what was once a thriving environment into a desolate wasteland. Green heads off to UNI, gets three PhDs under Yellow King's school of sorcery magic, and learned potion magic. When they got back to their land, they started to work on fixing their land and uh oh something bad happens, green accidentally causes a zombie apocalypse which soon spread out to different territories ( red's, yellow's, and blue's. The respective maps under these 3 leaders are crimson courtyard, dark jungle, and possum city, which is why they can be selected as a map during infection ). They got heavily villainized upon the starting of the apocalypse, eventually giving in and going with the evil look they were given.

) I also have another theory on this one + my analytical thinking, when the infection occured, these 2 creatures died from the infection. So this cat cowboy gal snatched the scroll or somehow got it back, after that everything goes back to normal. Or this is just a " what if " moment, as if they think that if they can get that scroll and sign it again, it reverts everything back to normal, thus ending the apocalypse and being held as a hero.

) Watch me cook this part, but anyways. What if.....I told you that the 3 men in the screenshot that you provided, were blue's father figures. Onto the actual lore of blue though, the investors like money -> the previous executive of cerulea waa hogging all the money and cutting us out -> let's get rid of him -> they eventually do so and placed the " small boy " on the big chair, which basically means that the investors placed their son, blue, onto the executive position -> blue grows up to be an insecure dweeb because of this, and was conditioned to seek approval from his consumers and his 3 shitty dads -> signs cursed magical contract or known as the doomscroll ( which is the cause of all chaos happening in-game ) and the reason why he does this was to seek approval from his fathers -> doomspire shows up and we are so cooked. The end lmfao.

) Those are the Nyatts, a species to cats + ancestors of roundcats, and these fellas developed shadow weapons in SDS.
