David had never heard the name Psyche before. He had no idea who that was or why Gaius would hate her enough to chase her down into the mortal plane.
What he did know, though, was that Gaius had only ever stepped into the mortal realm twice in his last timeline.
The first time was when he opened the first demon rift into their world, Earth. That was when all hell broke loose, literally, and humanity started dying like flies in an inferno.
David Knew Gaius was the root of this problem, which was why he was trying to become powerful enough to force him to stop. His plan had been this all along.
Get strong and either force Hades to act or take over his domain and act against Gaius himself.
But it was a plan that required a lot of time—and every second lost outside New Eden reduced his chances of success.
