This is a tribute to one of the worst civil massacres in the history of the United States.
In July 20 2012, a massive shooting occured in Century 16, a cinema in the Denver/Aurora metropolitan area. The suspicious killer, James Eagan Holmes, entered the cinema during the premiere of the movie
''Batman: The Dark Knight Rises'' with multiple weapons, like tear grenades, killing 12 and injuring 58 others. This was one of the most horrific massacres in the USA.
R.I.P to all the victims.
P.S: When looking for more information, I discovered a possible legend about the Denver International Airport KDEN. Some people say that it's an anchestral temple of aliens or native americans.
