DISCLAIMER: I DON'T OWN ANYTHING FROM ATLA
(Gao is wearing a brown coat with a stuffed hood and snow boots, there was no interaction between Katara and Gao because he is a full stranger, and he asked a delicate subject for her in the village, we are still a day before Aang shows up).
After Katara left, I begun the exploration of the ship and found a couple of broken traps that were ruin by the years in cold or were activated by animals, the exploration continue on the crew's quarters and then the bridge were I was able to see the horizon and Sokka's village, it took me several hours to remove decades of snow from the lower levels so I could reach the holding cells with the hope that something about the missing member was there, the ship was to old to be standing and the traps were efficient against intruders back in the day but I could feel something in the place like ghosts or that weird feeling that someone is watching your back however places like that will always have a dark history, I reached the holding cells only to find that it was the most dangerous place in the entire ship because it was full of all kind of traps with that thought on the back of my head I was sure that the Fire Nation wanted to keep intruders outside or keep someone inside.
"Hate when the paranoia hits hard!" I shout out with only the echo to answer me, while I started to move through the cell block, I heard something at the cell on the middle of the place and with my heart bouncing around I pulled my sword out while approaching that cell.
"AAAAAAAAAAAAAAAAHHHH!" could be heard in the entire ship thanks to a penguin jumping out of the cell as soon as I manage peek inside the metal box.
"I WILL KILL YOU DUMP PENGUIN!" I said out of anger and empty lungs, after taking a few minutes to recover from the scare I received the exploration concluded because I found a cell that has at least 3 traps on and the door was impossible to open.
It was easy to deactivate the traps, but the only challenge was the door, I pried it as hard as I could with a piece of metal that was found beneath snow only to have success after a long time of pushing metal with metal.
I was sad thanks to what it was inside that cell, the skeleton of one of my sisters chained from the foot like an animal, the uniform could tell me what gender she was, there was no sign of struggle so she died out of hunger or thirst which is no way to leave this world, after putting her bones in a bag with the idea of burying her somewhere near I took a scroll from her dry also cold hands, it was a final message to the anyone:
To whoever finds this scroll.
I am dying protecting my beliefs and my sisters, I am dying with regrets, I serve an order that will change the world, but I am in this situation thanks to them and that is a regret that I wish I would not take to the tomb but is too late for me and for them.
I want revenge on those who left me to die, I know secrets, secrets that no one should know, the Order's past is one of the darkest secrets in history, I manage to find a clue about our past in one old hideout and if I recall right the clue pointed towards the insignia above the throne of Omashu.
AVENGE ME AND MY FAMILY, WE DIED FOR SO LITTLE IN A TYRANT'S GAME.
"I hope your soul is at peace now you traitor, this scroll could have been our end" I said in shocked and in anger, I left the cell and headed to the entrance of the ship thinking what horror she lived in order to want the deaths of thousands, the death of her family, the thought was too painful, I dug a hole and bury the bag of her bones next to her cold tomb of metal, darkness was upon me so I went inside the ship to find a working bed and it didn't surprise me to found the bed of the captain in good shape, I reinstalled all the traps to avoid any surprise because I wanted to sleep and more with the emotional day I had.
