Prince (The Phantom of the Music Hall)
From Tardis Wiki, the free Doctor Who reference
A Prince of Calamiño was an alien whose rocket ship crashed on Earth. He awoke from his stasis in 1894 and discovered the Palace of Wonder was built over his ship. He used a camouflage enhancer to scare the patrons in an attempt to chase them out so he could leave Earth. Vastra, Jenny Flint, and Strax discovered him after Faye Garrideb requested their help in solving the music hall's hauntings. He was forced to destroy the Palace of Wonder in order to leave in his ship. (PROSE: The Phantom of the Music Hall)
