The captain of a Kantare supply vessel wrecked on a barren planet, who appears alive to the Enterprise crew but is in fact a hologram of a man long dead.
Kuulan appears in Oasis. When an Enterprise team explores a ship rumoured to be haunted, they find a small community still living in it, growing food in the hold. Kuulan presents himself as its captain and tells them the crash happened only a few years earlier.
The evidence says otherwise. The wreck has been there for more than twenty years, and T'Pol finds the remains of the real crew, Kuulan included, in a sealed compartment.
The truth is that the engineer Ezral and his daughter Liana were the only survivors, and that Ezral built holographic versions of his shipmates to give the girl company. Kuulan and the others vanish and reappear at his command, and help defend the ship before Tucker persuades Ezral to repair it and go home.
