"Now, a small team must land and journey on foot across the surface to learn who built the hole and why. ... For some the mission is the dream of the lifetime, for others a risk not worth taking..."

Who assembled this team? Were they just the closest to the site? Why wouldn't they all be excited to investigate? What's so risky? I ask out of confusion, not intrigue.

"Each step they take toward the mysterious abyss is more punishing than the last. And the ghosts of their past follow."
