I was born in Hogsmeade in late 1924, and was in my final year at Hogwarts when Grindelwald was finally defeated. Since then, I have steadfastly followed Albus Dumbledore in the fight against the Dark, and never regretted it. A member of both the first and second Orders of the Phoenix, I am quite familiar with Voldemort's capabilities, especially since I went to school with his alter-ego, Tom Marvolo Riddle.
*NOTE* - Obviously, this is not the "real" Minerva McGonagall. Rather, I, DSDragon, play her for the RPG community Inflecto.
