The Zohar says that many who escaped the destruction of the Tower of Babel did so by
relocating to Inner Earth. Inner Earth has long been said to be the domain of the fallen
angels and the Nefilim mentioned in Genesis 6. Inner Earth is said to also be the domain of
many animals which we have long considered to be mythological, such as the unicorn, the
phoenix, the minotaur, centaur and dragon (ref. Hesed L’Avraham 2:4).
