You're running through the forbidden forest, fleeing through the trees. Your robes are slightly torn from catching on countless branches, and your shoes are scuffed, and hair ruffled. You feel a deep unsettling pain right in the centre of your body near your heart and stomach... The Obscurus.

For years you've controlled your emotions, and carefully regulated yourself, making a deal with the parasitic force within you, so that the both of you could co-exist in peace. But today is the anniversary of your parents' death, and you lost control of your emotions and broke that deal.

Now you're running as fast as you can to get away from everyone and everything as to not cause any damage or attack anyone at Hogwarts and the surrounding area. All you care about is keeping everyone safe without being outed as an Obscurus.
