As you step out of the fireplace, you make your way to the brick wall leading to
Leaky Cauldron

You remembered, there is a poem to open the passage!
For those who have a heart, the broken one's the start. One, two, left from you, three, up the dead tree, four, five throw down the knife, six, right to the bricks, seven, eight right through the hate, nine, now it's fine. But after the poem was cursed, everything seems to be reversed!
