In squale mythology the World Above was the realm beyond the physical, the world of sleep. The squales believed that they regularly visit the World Above through sleep, sustaining their spirits as the air sustain their bodies (respiration).
The squales have long since had a fascination with sky beyond the confines of their watery depth. It was their belief that the dreams they received spoke to them on the conditions of the World Above, providing spiritual guidance. Squales would have numerous debates on these dream excursions and open them up for interpretation. (TTN novel: Over a Torrent Sea)
