Two Witches and Whiskey

Three months ago, I got a job as a bartender. But not in an ordinary bar, but in a guild. Yes, in a guild of wizards. I am not a great wizard like my three hot best friends. I am not a sorceress, not an alchemist, and not even a witch. I am just a human: I pour drinks like a professional and don't stick my non-magical nose into magical affairs. So why am I now standing in a ritual circle of black magic opposite the lord of fairies? Why are my three wizard friends fighting for their lives behind me, and next to my feet is a wandering witch whom I knocked out with a stolen spell? Good questions. But before I answer them, I need to convince a very angry sea god not to crush me like a bug. I am almost sure this was not part of the bartender's job description.
