Sheryl will be spending most of her time trying to do this, trying to look for anything she recognizes or can familiarize herself with!

As she grew up a street urchin on a heavily industrialized city-ship and has spent literally her entire life in space up until coming to Acata, I imagine she has general lockpicking/breaking prowess, and is in general very familiar with this level of technology. If all else fails, she's going to try to focus her music power as much as possible and create big vibrations to try and damage/destroy any locks.

Her primary goal is to be orienting herself and the team in terms of where everyone is on the ship/the ship's layout, and maybe finding some alternative routes like access tunnels.
