X-Men characters belong to Marvel comics, unless noted by me in the begining of the chapter.

The breath of the morning sun arose over the mountain shining on the lake below, but another breath was being taken far below the water's surface: the breath of a woman who had not inhaled deeply for months. The woman drew in her first conscious breath of air and choked through the musky heaviness. She opened her eyes slowly, feeling slightly pained, but not from light she expected to see, because there was no light at all. The muscles around her eyes hurt after the prolonged lack of use.
Once her eyes adjusted, she realized she wasn't anywhere she expected she should be. In fact, she had no clue where she was. She began to feel extremely claustrophobic. All she knew was she was incredibly confined and she didn't like it. She had to get out and she did. She focused all she was physically and mentally and broke free of what was restraining her to find herself surrounded by water. Completely panicked, she didn't know what to do other than just lay still. Common sense told her she would float to the surface, and she did.
