Raxu obviously didn't know that the terrain would act to his disadvantage. But it was rather common sense that existence of an open hot spring and the rocky texture in the surrounding hinted that the land was close to groundwater.

The open hot spring has relaxing body temperature, but the closed groundwater didn't. Its temperature was volcanic, and the terrifying heatwaves crashed on the circular barrier surrounding Raxu.
