The horse had been a little nervous, but Fred had managed to coax him
across without too much difficulty. "I wonder why they went to all that
trouble," Astra said. "Wouldn't a conventional bridge have been simpler?"
"Perhaps not, if their magic is advanced enough. Building a bridge across a river of any size is quite a big job. This might have been much quicker and cheaper." "So why not leave the magic bridge in place permanently?" Astra wondered, looking back over her shoulder to where, now that they had crossed, the stones were automatically resetting themselves and the bridge was disappearing. "I suppose they hope that they may be able to keep out some undesirables. Wild animals, perhaps, or maybe trolls or something like that, as I can't imagine so simple a puzzle keeping many humans from crossing. Or maybe there's some undesirable side effect from leaving it 'on' for too long?"
