Secret Treasures (Patreon)

a woman with many possessions needed to make sure her stuff was safe and soun, in a place where nobody could find it easily. She knew a cave deep inside a lake, so sailing! there seemed like a good idea, as not anybody she knows really knows about the cave.

Little did she know that her tank was sabotaged by someone interested in her treasures, and only figuring this out too late, she realized her tank was no longer giving air halfway through.

Inevitably causing her to become a missing treasure in the lake, along side the treasure she left hidden.
