As a Gryffindor student, I loved doing adventurous things during my teenage years, but I did nothing too life threatening. That was until I graduated and became an auror. Now you may be thinking, "Oh, so that's how she died." Well, that assumption would be wrong. My untimely death came a year after graduating when a few friends and I decided it would be a bright idea to see who could stay underwater in the ocean the longest without apparating out. Wanting to prove myself as the superior swimmer, I swam down a little farther than I should, and before I knew it, I was out of breath. I tried to say the correct spell, but the water kept changing my pronunciation, casting various other spells. Eventually I ran out of air and couldn't make it back to the air. When I died and became a ghost (1966), I decided to come back to Hogwarts, and to this day I still can be seen making the most of my time as a ghost. If you take a closer look, you will find that my clothing is still dripping water from my drowning.
OOC: The cause of death may change if I come up with a better one since I'm not happy with it.))
