Alright so before being swallowed by the Leviathan, a vex came into contact with the SIVA aboard the Exodus Black and becomes corrupted. Failsafe contacts the vanguard urgently informing them of a theft of her golden age tech, SIVA. The vanguard are shocked that SIVA was aboard the Exodus Black and immediately forms a fireteam with the directive to board the Leviathan, find the corrupted vex, and destroy the SIVA within before it spreads to uncontrollable levels. Inside the mouth of the Leviathan you'll find a chaotic landscape as pieces of Nessus float around inside and randomly form pathways for Guardians to follow. However, these pathways do not always stay put and will occasionally move without warning, possibly taking Guardians to other areas. Ultimately, everything should converge on the same point to reunite the fireteam. [spoiler]Think of it as a mix between the procedurally generated Infinite Forest and the staircase in Hogwarts.[/spoiler] The point at which these Nessus chunks orbit is an exit out of the mouth of the Leviathan and the direction which the corrupted vex managed to escape the mouth. You follow the pathway, going through the Leviathan underbelly and eventually finding yourself in the "courtyard" of the first raid. [spoiler]The place where players need to unlock doors to proceed to challenges.[/spoiler] Throughout both encounters, a mixture of vex, cabal, or SIVA vex/cabal appear to challenge you. The courtyard will be the final zone and will have a mixture of vex, cabal, and SIVA vex/cabal. The SIVA variants will not attack one another but other than that it's a free-for-all with all factions attacking each other. [spoiler]SIVA turned the Guardians against one another, so why can't it turn vex and cabal against each other too?[/spoiler] In this zone, after a short while, a SIVA vex mind will appear and destroy all vex units and cabal troops in the courtyard. This vex mind, after your carnage through the Leviathan following its trail, is the last vessel of SIVA and the boss for the strike. It could just be a generic battle from there: battle it while it teleports around the courtyard in an attempt to escape you momentarily [b][i]OR[/i][/b] the SIVA vex mind could teleport randomly into each of the raid encounter rooms with a smaller challenge to overcome in order to make the mind vulnerable again. Either way, the rest of the Strike pretty much goes as you'd expect. You fight, you win, Zavala expresses concern, Ikora shows interest in the SIVA, Cayde will most likely be roasted by Failsafe and then it's mediocre loot for days. That's pretty much it. [spoiler]Yeah, I like SIVA and I'm keen to see it ~consume enhance replicate~ the other factions >:)[/spoiler]

So long as pre nerf quadron is the end boss

Personally, I’d love to see a raid on the Leviathan!

I can see the Vanguard wanting our Guardian to take out Calus at some point but I hope we don't. I wouldn't mind seeing what Calus has planned for us, maybe becoming his Final Shadow?

we already have a strike in the Leviathan, is called Eater of Worlds

We already have 2 strikes on the leviathan. There hasn’t been a raid released yet. Just “trials of the emperor”

I have a good raid idea and I feel this is a great place to post it! It would be such a good addition to add a cabal capital in the tower as the raid area. It could be where we had to solve challenges to defeat the security system, and as a little boss, fight consul outside of the building with his security units. Especially since it always seems he is out working to smash the guardians who escaped. Finally the jumping puzzle could be us jumping into ghauls ship that’s parked just above the capital by jumping onto random destroyed buildings and debris. Finally once we get to his ship, there can be guardians bodies all over and for once have an interactive object in a raid by scanning a guardian. Finally we can still fight ghaul in his final setting in the campaign , since it looks so god damn good. Then we’d need to combine our supers and easily kill his outer shell, then fight his true form. I don’t have a true form fight scene but hit me up and I can post a post with the entire idea. Yes I’ll give you credit. Just a small idea but could’ve been cool.

Eater of Worlds makes Crota’s End look like a raid.😃

We begging for reskins now? Is it really getting that bad?
