He had his harvesting devices ready, so he probably killed thousands of leviathans on the first day, and destroyed millions of leviathan's orbs.
Right- globes. Thanks for reminding me about them

Personally I think that they're more recent (some 5 years or something

) innovations but let's say that Leviathans used them at pinnacle of their power. Problem is- they're maikng every attempt of defeating Leviathans doomed to fail.
So- let's say I'm Leviathan and I'm sitting comfortable in my house at the bottom of the ocean. I don't have to do anything- I've plenty of thralls, right (they're somehow able to live 5000m underwater. It's much more plausible than Catalyst words during ending)? Suddenly! My beautiful underwater house is burning (5000m underwater, etc

)! Apparently thralls have somehow managed to start a revolt! I'm terrified. We- Leviathans- are completely dependent on thralls. Our empire will fall without them. And even worse- my house 5000m underwater will burn!
But then I suddenly recall teleshopping advertisement (Ironically- "Leviathan" is network of shops in my country

). "Controlglobe in every Leviathan house!"- it says. "Are Your thralls constantly revolting? Are Your skills of controlling them weakening? Buy Controlglobe and sleep easily (or whatever Leviathans do instead of sleeping). Controlglobe is capable of taking control of every species- from Husk (what the hell is Husk?) to Reaper (what the hell is Reaper?).
If You don't know what Reaper is wait few millions of years- if You're still alive You'll know for sure. (they're working now- so Catalyst didn't found a way to prevent them from working)
So I runned (or rather thought- they're telepathic, right?) to my living room- to Controlglobe. And I taken control over those noisy and annoying (revolting) organics. Now they're rebuilding my house- it have a hole in a roof and water is pouring to my sleeproom. It's almost as annoying as this (shortlived) revolt was.
Oh- and in TV Leviathan reporter was talking about arrestment of rogue AI responsible for this revolt. Apparently it was shouting about being "vanguard of our destruction", and something about knowing some "Harbringer" guy.
Now seriously- if Leviathans really had so much of those globes, than every organic army trying to defeat them is under their control in no time. Unless someone have better explanation...
