The Southrons disappearance isn't such a mystery. In A Hunter's Heart, the episode opens with Helios attacking a village, where he finds Gwen. He's not just attacking the village to plunder it, he's forcefully conscripting the villagers.

Helios then makes a comment later to Morgana as Gwen is listening in, that he hasn't got all the men he needs yet, but they're getting there. Meaning he's planning on kidnapping more men.

So when Helios died, those forcefully conscripted men fled for their lives or just outright surrendered.

Why fight when the man they were kidnapped to fight for is dead?
