The Tirwells were one of the Unified Powers during the time of the Romans. They were accused of treason when Fut-Lung, one of the missionaries of the Chinese embassy, blamed them for a crime. They are of French blood mixed with the lineage of the Tar'ken aliens, whom are now presumed extinct. The technology of the Tir'wells surpasses the Owls, but they refrain from using it in wars. The Eiffel Tower is a prime example of French-Tir'well weaponry. The tower occassionally emits radiowaves that push mindsets into the French populace.
