The Smashing Scroll

An ancient curse sends a stone silo crashing across the countryside.  Houses, barns, and cars are crushed in its path.  The silo contains a giant scroll, sent by the foul Spellbinder to imprison the entire earth within its vast, unrolling page.  Even the mighty Librarian is overpowered by the Spellbinder's steamrolling magic.  Can anyone stop the smashing scroll?
