Demjely
From Tardis Wiki, the free Doctor Who reference
Demjely was the Geramon ambassador who greeted Bernice Summerfield when she arrived on Beedle. He kept playing practical jokes on Benny. When the High Japester faked the ruins on Beedle to attract victims for his practical jokes, Demjely sabotaged his departing ship and became the new High Japester. (PROSE: Beedlemania)
