Sweethearts are actually just Engineers from the Halo games, except shaped like hearts and with parasitic body horror. And also pumped full of cocaine.

On another note, I just remembered something.

“Established an army.” Tez snapped back. “Slain dozens of Hain villages and hundreds of Sculptors. You won’t be any challenge.” The Hand seemed to be drawing power, steadily, as Tez watched the Demi-god.

This is kind of impossible purely because of how ridiculously rare Sculptors are. Assuming a generous Galbar population of one billion mortals, and given the rate of one Sculptor per ten thousand mortals each, with a 100% survival rate, there are still only 100,000 Sculptors on the entire planet [i]before[/i] both Elementals and Realta started the genocide party.

So Tez probably hunted down a few dozen of them, which is still impressive. Good on you, Tez.
