The latter Undying King, after years of fruitless seeking of a normal path to contact the Nether River, devised an extremely insane and bold plan.
He began to establish the Council of the Dead and used the power of the council to continuously spread the faith and legends about the Nether River in the mortal world over the long years, in order to reinforce the concept of the Nether River as an anchor in the real world.
Eventually, after centuries of accumulation, He deeply bound the concept of the Nether River with his own spirituality.
Finally, He succeeded!
He forcibly ferried that river, which should only exist on the level of illusory rules, from legends to the boundary between reality and illusion.
Subsequently, He took a dangerous gamble, forcibly merging his soul and will with the Nether River that had been ferried out, successfully stealing a part of the Nether River's Position as This World's Only One.
