This became evident as Ikenga observed the enormous, grotesque plant he had created, which now bore one of his very eyes as a grotesque fruit. The plant, a testament to his power, remained oblivious to his presence, thanks to the applied curse that perfectly concealed him. He can perceive and interact with his creations hence why he could teleport here easily.
This limitation on his direct spatial influence also explains his restricted teleportation. He found he could not teleport from the Abyss or the goblin world. His unique form of traversal is confined to the corrupted land, a place that holds no inherent attachment to either the Abyss or the goblin world. This corrupted land is, in essence, a nature of its own being formed, not complete yet hence why Ikenga can easily influence or act on it.
