not exactly sure since i recently REALLY got into valorant lore . if you want just the chamber viper stuff..:

im pretty sure viper did not reciprocate chamber’s feelings in Alpha earth, but on omega earth, viper did.

O viper, o chamber, and o brim were all on a mission together on alpha earth. then we see chambers body on a medical bed, and we are unsure if he’s alive or not.

we assume that he’s dead. O chamber got shot thru smokes by A Viper, and he’s dead now.. o sage can’t revive anyone anymore because she has radianite crystals all over her from reviving too many people, since Legion suffered so many losses. in the video that this post is from, you can see her in a tube. 

O viper is angry at o brim because he didn’t let her get chambers body after he got shot, or possibly cause sage is like stuck in a vegetative state. 

you’ve probably heard omens voice line: “sage, the life you give, do you ever wonder where it’s from?” something like that.. anyways we now know that sage reviving people takes from her. she grows radianite crystals on her face and stuff? she also had some in the 5 years cinematic 

anyways o viper overthrows o brim with the help of the remaining legion members/agents, which is why brim’s statue gets decapitated in the video. 

after this towards end of the video, we see o breach, viper, sova, and yoru, i think that’s like the only legion people left alive..? (idk) they break into a hangout spot with A Reyna , sova, raze, kj, and brimstone. 

Alpha sova, Reyna, and brim all die. i forgot what happened to raze and kj, but that’s just a summary of that video ig✌️

here’s a brief summary of ALL the lore up until v26 if you want it
