Edge should have just went with Gash. It would have been better than an abrupt death or being suddenly erased from existence. Sure the Tower network would still be enslaving mankind; but with Azel that could have changed.
That’s why sometimes, I can see the value to Craymen’s decision to want to control the towers. They were keeping a dead planet alive. What if shutting them down like Gash and the Seekers wanted, ultimately ended up killing the planet and drove everyone to extinction?! All one would have to do is stop the production of pure type monsters. That way humanity wouldn’t have to live in fear of population control.
And it feels like what Edge did according to Orta’s storyline, was temporary. And for all we know the planet could have been dying. Some towers and monsters where still active anyway, despite shutting down the Sestren Network…As if the network itself had a backup generator or reboot program.
