Later folklore, dating at least to the Nihon Ryoiki of around 800, credits En no Gyoja with supernatural feats performed in the mountains, a documented legendary layer distinct from the plain judicial account of his 699 banishment recorded a century earlier in the Shoku Nihongi. The tradition that grew around him itself acknowledges that record and legend are inseparable in every surviving account of his life, a documented admission distinct from a tradition that presents its founder's biography as settled historical fact.
He is traditionally credited as the founder of Shugendo, the mountain ascetic practice built on that same layered record, a documented founding role distinct from a tradition that names no single originating figure at all. He is venerated today as Shugendo's founding patriarch at sites including Kinpusen-ji and Ominesan-ji, a documented living veneration distinct from a founder remembered only historically with no continuing devotional focus.
That a figure first recorded in an eighth century chronicle as a man banished for sorcery is venerated today as the founding patriarch of an entire mountain ascetic tradition at temples still active in his name, marks En no Gyoja's case as a documented instance where a legendary elaboration built up over centuries, by the tradition's own admission, has become inseparable from whatever plain historical record came before it.
