The river Styx can be located in remote regions dispersed throughout Bal-Kriav. On this world, one of the most renowned sites to observe the river is the Styx Fountain.
The waters of the river Styx exert a formidable amnesic effect. This influence is exceptionally potent (Will DC28), causing those who fail their saving throw to forget everything they know, aside from basic instincts. Psychic surgery or a healing spell can restore the patient's mind, but there is a 10% chance they awaken with some form of insanity. Attempting to remove the insanity is hazardous, as the caster risks contracting the same affliction (Will DC25). Specialized, dweomer-preserving containers (valued at 1,500 gp) are necessary to maintain the Styx water's properties, yet even these deteriorate rapidly (the DC decreases by 2 each day).
