Descent into Darkness (Major Spoilers for House of Ashes)

The story follows my OC and US Marine Gabrielle Foster.

At the end of the Iraq War, Special Forces hunting for weapons of mass destruction unearth something far deadlier than what they expected, a buried Sumerian temple containing a nest of ancient and unearthly creatures. In order to survive, they must forge an alliance with their enemies from the world above.

Once again, like the title says, there will be major spoilers for House of Ashes here. If you haven't completed or watched the game yet and care about spoilers, I highly recommend going and doing that first before reading this fic.
