Book: Crucible Arenas.
ARENA DESIGNATION: First Light
LOCATION: Mare Cognitum, Earth's Moon
What was once an unassuming exobotany laboratory complex turned into ringside seats to the end of the world during the Collapse. Immense fissures in the Moon's crust spew a sickly yellow miasma, and hint at the utter destruction going on deep beneath the surface. Whatever the Hive are up to, they've been at it a long time, and they're not overly concerned with keeping Luna in one piece.
