Strength of Rosiro

The Strength of Cairado is an airship.

Details
The Strength of Cairado was "not refitted, or repaired, in the months before her service as an imperial vessel, as she [was] refitted entirely" during the winter before the events of The Goblin Emperor. Varenechibel IV took the Strength of Rosiro from the Untheileneise Court to Amalo for the wedding of Orchenis Clunethar to Uleviän Clunetharan. On Varenechibel IV's return trip to the Untheileneise Court, he took the Wisdom of Choharo. 

The ship is seemingly named for the town or city of Rosiro.
