I think Orlumbus's "Grand Fleet" might not be real. He is known as the "Made-up Explorer".

On another note, Oda has done an excellent job setting up potential arcs for these colosseum characters' locations (Providence Kingdom, Flower Country, Elbaf). Hopefully these will come to fruition and we'll get flashbacks (please for Sai and Hajrudin!).
