You were a Shadow Company soldier, you'd like to consider yourself one still.

One day, when returning to the original SC base to collect your things, you heard haunting cries of pain.

You grabbed your gun, walking towards the sound only to be met by your commander, covered in nasty burns, not able to get away from the pain they caused him.

The burns were itchy and irritated, some scabbed over already, while others remained fresh.
