Black Sail, Elizabeth.
Black Sail has controlled the Wood Elf Plane for decades and has already established a stable Space Transmission Array.
Duke doesn't need to take a Space Airship over; he can reach directly through the Teleportation Array.
The cost of this cross-plane teleportation is generally not low, but since Duke is on office errands, he naturally doesn't need to pay.
Unless he has some personal need to go to a specific plane, then using the Teleportation Array would require a fee.
The Elizabeth, as Morgan's vessel, is also the most important place of the entire Black Sail.
All Under-Black Sail Plane Teleportation Arrays are here, and the Teleportation Array to the Beastman Plane is also under construction, expected to be successfully set up soon.
Duke brought Yala to the Teleportation Array of the Wood Elf Plane. In Black Sail's view, Yala is Duke's personal property, so she can transit through the Teleportation Array together.
