Rowan watched Telmus and his daughter overhead with a fair bit of amusement as they looked around his realm, and they saw the echo of him that was left in the past.
Because he had spent so long sitting in one place when his Origin Land was recreated around him, and he unleashed substantial energies of creation and destruction in this place, Rowan had left a stamp upon his realm, an echo of his presence that was so real, even Telmus could not discern that the Rowan he was acknowledging was a memory of the past.
His amusement largely stemmed from his memory welcoming Telmus and initiating a conversation with him, and so Rowan waited to see how long it would take Telmus to realize that he was talking to a memory.
After watching for a while, seeing the way his memory was able to perfectly interact with Telmus while showing him around the realm, Rowan figured out that it was impossible for Telmus to discover he was talking to a memory, at least not when he was inside the Origin Land.
