It all started, as all good field trips are want to do, with a trip to a field.

Well, more specifically, it had been to a strange underground temple right UNDER the field, on the outskirts of Ponyville.

Rainbow Dash had taken a class from the School of Friendship down to the ruins to explore, partially to help with the whole cooperation and teamwork thing that friendship is all about, but also to indulge her inner Daring Do fan-filly regarding these ancient ruins. And as long as the students didn't catch on to things like how they were only painting the fence or waxing a wagon for a two-for-one deal and not for a friendship lesson - or karate - just about anything went.

It had gone well - right up until the moment a fight between Gallus and Smolder broke out (it had something to do with gingerbread spiders, apparently) just as the group had made their way straight to the heart of the temple, and it was during their ensuing scuffle that they knocked over what looked like a priceless pottery piece, causing it to shatter on the floor.

Rainbow Dash, being such a fan of Daring Do, would have declared this moment the exact point in time where all the booby traps in an ancient ruin would suddenly activate and attempt to end the heroes right then and there, and because nopony would ever want this temple to be accused of not following tradition, the walls start to shake and rumble, and two wisps of a weird purple gas escapes the shattered pot.

Taking the class to safety, Rainbow leads the class right back to the first room they entered upon reaching the ruins, which has five different corridors, including the one they just came through. One of the corridors leads back outside, while the others are dead ends (or at least they wouldn't be if they weren't currently attempting to flee for their lives and there were time to study the murals on the walls). 

Rainbow spots an ancient clock at the centre of the room, telling her she's only got an hour left before the temple apparently collapses and future archeologists find their remains and put their decayed forms on coffee mugs and mouse-pads in tourist gift shops. From what she remembers from the trip, she reckons there's just enough time to explore one corridor, return to the room to report and then escape back outside, as long as she splits the class off into groups. There's nine of them, including herself.

Unfortunately, nothing seems to ever be that simple. The corridors are just too narrow for Rainbow to fly at speed, and from the murals' description (helpfully written in the modern tongue, which was useful since Rainbow wasn't an obsessive nerd who messed around with hieroglyphs) the two wisps of smoke were in fact the vengeful spirits of an ancient high priest Tim (of Tep) and his lover, and they would possess travellers and lead them to their doom, involving a disturbingly high amount of scarab beetles.

Rainbow realises that two of the class are possessed, and could lie at any moment, but they may also tell the truth - nopony could ever accuse them of being impractically evil. As they won't lie all the time, Rainbow has no way to tell them apart, except for the fact that she definitely isn't possessed, and that she's the only one in the room aware of the curse.

And so, to avoid a rather grizzly end (and a rather awkward parent-teacher conference afterwards), how should Rainbow Dash play this in order to make sure she and the class get back in one piece?
