The ground slowly parted.
I heard the slightest crack sound in my ear. "What's happening?" I nervously asked my scared friend standing next to me. "It looks like your house is going to collapse" he replied. I stared anxiously at the old, creaking wall of the enormous house,I felt as if something very bad was about to happen...

The ground started to shake a bit. " I think we should go outside" I said. The crack got bigger and bigger before we realised that there was a portal there, right in front of our very eyes. "That is so cool" said my friend excitedly. "This will lead to a brilliant adventure!"...
The mysterious crack!
