historians. According to Antoniades, the team, researching Celtic culture and the Celts' views on mental disorder, found out that they used the term "gelt" for a person who had been driven mad by a curse, grief, or the trauma of a battle, and that the gelt would take to a life in the woods in search of penance, punishment and purgatory; the team decided to make Senua a gelt, who had left her home in exile for those reasons.

[...] To complete Senua's quest, you have to internalize and accept the logic and meaning behind these things to progress"; he notably felt that using the tendency of certain psychotics to see patterns others would not see or notice as a game mechanic to solve puzzles would provide a unique angle impossible in media other than
