As Phasma rose up out of the disgusting brown liquid that some might call "water", she was angry. The traitor FN-2187—who now called himself Finn—threw her into this trash with the help of his new friends. The nerve of those… They would pay, but not now. Now she had to get out of here.
She quickly noted that her visor had muck on it, so she couldn't see very well through it. She took it off, making a mental note not to court martial herself later. While it smelled horrible, her sense of smell could be ignored in this case in favor of sight, and the helmet only mitigated the smell slightly. She wouldn't be able to clear it, what with the rest of her being filthy, so she would just have to carry it out of there and clean it later.
She quickly took note of her surroundings. She remembered that they reused the designed from the original Death Star, as there wasn't really any reason to change it. The refuse was mostly industrial waste from the recent construction of Starkiller, though there were some other things in it as well.
There was a strange tingling in her hand, and she checked it out. The impact of falling had fractured the casing of her left crush-gauntlet, and fluid had gotten through the waterproofing, causing it to spark. She was glad that it was broken instead of anything else, especially from that fall.
There was a strange, bestial sound echoing through the compactor. She wasn't sure what it was, but it might not have mattered. Then again…
She felt something swim next to her leg, and she quickly grabbed it out of the water. It was a strange looking creature with one long eyestalk looking at her, and the rest was under the water. She looked at it calmly, and squeezed the life out of it with her functioning crush-gauntlet. She discarded the disgusting thing, and moved on.
She went to the door. She had the codes to open it, and began to type them in, when a mechanical sound shook through the room. The walls began to close in, and she tried typing in the code faster. Unfortunately, the code didn't work if the compactor was turned on, so the door wouldn't open!
She had to turn off the compactor before she was became a stain on the walls. She grabbed at her belt for her commlink, but it must have fallen off in the murky waters, so she wouldn't find it. Her helmet communicator wouldn't be able to get through the walls or the door due to its low power. She would have to turn it off from inside the compactor or think of something else.
As the walls closed in, she put her feet up against one wall while having her back to the other one, holding onto her helmet with her left hand. While it was futile to try and stop it this way, that wasn't her objective. She began to climb out of the compactor in that position.
When she got up to the chute, she slipped and began to fall. She grabbed onto the wall with her crush-gauntlet, forming a small handhold. Despite the weight of herself and her armor, she was able to hold onto handhold. She then pulled herself up, put her arm up on the chute, and then quickly switched her functioning crush-gauntlet to the chute before she slipped. She then pulled herself out of the chute just before it closed behind her.
After the compactor opened up again, she jumped back in. As it finally settled down, she put in the code to open the door, and got out.
When a pair of Stormtroopers on patrol encountered her, she said, "Troopers, there are intruders on base. Kill on sight."
