One night, Jabe was going through his stolen spellbook, looking for anything in the old tome that could be useful to save.
"'Delightify'? no... 'Insta-die'? no no... 'Hideoustus'? definatly not!.. 'Enormibus'... Oh! What does that one do?"
Though it was hard to make out words in the dusty book, out of curiosity he tried to decipher the ritual required.
"String of hat... Tooth of bat... Whisker of rat? That's easy-Ow!"
So easy that he just had to try it. Using some ritual chalk, the circle was quickly drawn as instructed on the next page. With the components properly placed, he began to chant;
"Amplus tripudio seismela stemoro!"
The second he finished, both the magical circle and the rat himself started to glow.
"Whoaa-"
As the components dissapeared in a brigt glow of purple light, Jabe could feel that he started to grow. His room became crammed as his muscles
bulged in size. He had become at least twice as big as his original size, and scrambled around in his now tiny room looking for the spell book.
"Haha! This is great! I'm definatly going to mark this page. Now, how do I shrink back down again?... WHAT!? AN ENTIRE MONTH?"

Huge huge thanks to the amazing  Hom.nom.nom for this wonderful commission!!
