Taboo Realm

The Taboo Realm is the mysterious prison where peak-level cultivators from the myriad worlds (ex. the 3,000 Worlds) separated by Chaos will be sent after their comprehension and utilization of the 3,000 Grand Daos have exceeded the limit of what the laws of their world will allow. Likewise, each of the cultivators stranded here is immensely powerful despite their different cultivation systems (ex. Open Heaven Realm for Yang Kai). However, once a cultivator is sent to the Taboo Realm, they will be rapidly forgotten by their homeworld. Therefore, unless a cultivator can break free from the Taboo Realm, they are essentially "dead" to the rest of existence.
