Eshana and James are nomadic humanoid travellers. They specialize in the design and creation of regularly spaced sound waves that create a pleasure response in the brains of nearby beings. On their home planet, this practice is known as "Music."
They have been known to encourage unsanctioned non-conformity in the form of laughter, dancing and questioning reality. The Galactic Federation recommends that they be approached with caution.
They themselves recommend that they be approached with free food or a round of drinks.
