Ok ok from what I can gather and what I’ve read this season is gonna involve the cabal. But since Outbreak Perfected is here I have a big theory. Remember back on Nessus when Failsafe said [quote] “Accessing Node 9875A. File header: SIVA Project. Files locked behind Epsilon Theta encryption A, D, and G. No decryption schema found."[/quote] Failsafe Mention Siva, Siva was made during the “Golden Age” also when the Exodus Black launched and crashed. Long shot, could they had Siva aboard the ship and had it safely contained? We know that Siva is somewhat gone on earth after the Wrath of the Machine Raid. But this Siva wasn’t on earth at the time so their is sill Siva out there, especially with the rise of Outbreak Perfected. Furthermore on how the cabal gets involved. When the Leviathan came to Nessus and ate chunk of the planet. Remember that lead to the plot of the first Raid Lair. Could the Leviathan ate the “was contained Siva” and is now possibly spreading inside the Leviathan? I feel strong with this theory due to that bungie has hinted Uldren’s return back at his old ship that crashed in Ma'adim Subterrane Lost Sector. (I couldn’t find the quote from the scannable). But my conclusion though - Siva is probably back - If so Leviathan ate Siva - Siva on Leviathan spreading
