Summary: This is a crossover between Tamora Pierce's worlds of Tortall and Emelan. Thom and Tris create Portals to each other's worlds, but the spell goes wrong and causes mass chaos!!!

Disclaimer: I do not own Tortall, Emelan, or any of the characters. That right belongs to Tamora Pierce.

A/N: I'm not gonna go through every story just to see if this has been done, so if it has, I'm sorry. Also, I am writing this with my friend, so if it seems weird, or the chapters seem drastically different, shut up and live with it, or don't read.

Rated T for safety.

Prologue 1

"Let's see..." mumbled Thom to himself, leaning over his spellbook. After a few minutes, he transfered a couple of equations to his notes, reviewing the last couple pages. Nodding to himself, he stood up and carried the pages over to an open space with markings on the floor – his work area. He knelt down to study the markings, making a few changes with a piece of chalk. Then Thom stood up and, taking a last look at his notes, recited the incantation.

"Eht otl Atrope ht tel Rofde-Nepoe bd lrowre, tla emi tfotnuoma deific ep Seht, tel nos repdeific Epseht. Rof ot nward eb rehto on dec Neulfn, ie br olatropeht en Ont Elstcef. Fes tiyb..."

The spell continued for several minutes, with Thom deep in trance. Every now and then, he reached into a pocket in his robe and scattered a handful of different colored powder onto the chalked floor. When he was at last finished with the incantation, he opened his eyes and reached behind him for a match. He grabbed it upside down, and lit it on the table as he drew it towards him.

In the process, Thom knocked over a container of Nellek, a mixture of Haneen root and Wodahs juice. The Nellek, which contains almost the exact same chemical composition as sea water, spilled over the chalk markings on the floor, essentially ruining the spell. However, it was too late, even if Thom had not been under the spell's influence and had noticed. He placed the match on the floor, and the powder burst into flame.

It flared up and spiraled within the chalk circle, then turned into ash and scattered to the floor, leaving behind a clear, flat surface.

Meanwhile...

Tris was in a cave by the sea, meditating. At least, it seemed like that from a distance. In reality, she was muttering an incantation beneath her breath, every so often scattering minuscule crystals, almost as small and fine as powder, across a circle drawn in the sand in front of her.

"Eht otl Atrope ht tel Rofde-Nepoe bd lrowre..."

She reached into her shirt and pulled out a match, lighting it on a rock beside her.

However, Tris had miscalculated the time, and the tide was coming in.

A wave of seawater washed over the circle before retreating, and right before Tris touched the match to the crystals. The flame flared up and spiraled before turning into ash and fluttering to the ground. In a detached place, Tris recognized that the spell was ruined, but by the clear, flat surface in front of her, she suspected her fears were unbased.

--------------------------------------------

At the exact same Time, in two different Places, the spellcasters looked at the Portals, and slowly reached out a hand to touch them. At the exact same Time, they touched the Portals, and in a flash of bright blue light...

Thom and Tris switched Planes.
