Carrowhulk

Carrowhulks are constructs used for transportation. They were common in Avalir during the Age of Arcanum.

Description
Carrowhulks are quadripedal and have velvet benches on their backs. They are used for public transit. They glow, and are reminiscent of large creatures such as elephants. They can speak, although thus far they have only been shown to say advertisements. The benches can also be replaced by beds, as when the Golden Scythe sponsored carrowhulks for transporting people from the pre-Replenishment parties.

Trivia
Aabria Iyengar compared carrowhulks to the Cat Bus from My Neighbor Totoro.
