Disclaimer: I don't own Harry Potter

He resides in the dungeon

Where potions of all kinds brew

His dark past keeps others at bay

The Slytherins are his minions

Gryffindors are his enemies

Hufflepuffs are weak

Ravenclaws are know it alls

He's every first years' nightmare

The Half-Blood Prince

He watches over the-boy-who-lived

The one with his arch enemies' flesh

And his first love's blood

To everyone he is cruel

A frightening figure

The potions master

Only Dumbledore knows the truth

Will else anyone ever know the same?
