Supernatural being who recently became interested in mathematics while in, of all places, Baltimore, after my 2013 banishment.
Each year, I am banished from Detroit, Michigan, only to return a few weeks later and wait to be banished again the following year.
I'm looking forward to my 2019 banishment, which will take place on March 24. See https://www.marchedunainrouge.com/ for more details. I will stay banished for at least one week, and return in at most three months, leaving plenty of time for my 2020 banishment.
