Regarding the Weapons:

(I forgot their names, derp.)

Au'ra in Red was the Ruby. Blue haired Au'ra said he pilots Sapphire. So my guess is that green haired one will be Emerald and then BOTH the white haired will pilot the Diamond weapon. That's my genuine belief of what's going to happen, either that or the one that was happy to see Gaius ends up sitting out of that one.

Eden storyline:

Love the music and the boss design and mechanics. I'm not exactly a fan of Gaia's story in the way they did it:

She went from recovering from the battle to fully healed and in her unique outfit. I would have preferred we were there when she regained consciousness, is distant, and then goes to Eulmore and gets her outfit and shows off the personality she has. As is I feel like she suddenly got dumped on us without a proper introduction. Purely my own personal opinion. Also her and Ryne are adorable together, I totally ship them tbh. I'm wondering how the story will conclude and while I have a few theories I'm excited to see what will happen in the third raid tier.

MSQ:

Goddamn, there's a lot to unpack here, I'm not even sure where to start. First let me say that I didn't think the new MSQ got remotely interesting until the dungeon where we got some pretty huge lore reveals in every cutscene that followed with some massive lore implications. My standing theory is Eli is trying to trigger another flood of light by tipping the scales again resulting in us (the WoD) against the new WoL's to make sure that the balance is maintained.

I'm still processing the entire Echo thing, I'm not even sure where to start but I REALLY wanna talk about it.
