Porto is the only known survivor in the Slovatik mines. She may have inhaled Ghast.

Porto is a playable character in Killswitch. She is a young woman, probably a miner in the Slovatik mines. She dons odd apparel for a miner, a dress and short-sleeved shirt, apparently. It's assumed that Porto inhaled Ghast(and therefore gained her size-changing properties) at the end of Ghast's story, but no one really knows. [1]

At some point in her past, Porto somehow developed lockpicking skills[2], which may imply a criminal past. She also had some connection to the Unnamed Slovatik Worker, although whether they were friends or just co-workers in unknown.
