Cathal is not for the beginner. Cathal is Dullahan. A Dullhan is a dark, or evil fairy/demon . Some believe that this type of fairy originated from demons. Cathal is extremely strong willed and very active. I would strongly advise that when engaging with Cathal to be very polite and respectful...he will NOT respond favorably to demands. Once Cathal has accepted you, he is very loyal and protective...as long as you remain respectful. Cathal has no problem inflicting harm to your enemies and LOVES playing pranks. He has a very wicked sense of humor.
