Martin and Rianna walked through the mountains, holding each other loosely. If they weren't in an Arena where they had to fight to the death, the sight would have been rather beautiful. They tried to not think about the fact that one of them – or both – would most likely die. So instead of making small talk, they remained silent as they trudged on.
As they walked, the skies became darker, and the air became chilled and thin. Soon, they were able to see their breath when they exhaled, and they both were shivering. They knew what it meant, but they continued on anyway. Both of them knew the spell, so if there only a few of the beasts, they would be fine, but… even with their pride, they clutched their wands tightly, their knuckles white.
And then from the horizon they saw it – the cloaked reaper that yearned for their souls in exchange for a kiss. Both of their bodies became frigidly cold, and they could see images that made them cringe – their parents, tortured by Death Eaters, their yells piercing the two of their ears. Martin's older sister thrown to the ground and a flash of green light wiping the life from her eyes. Rianna's younger brother thrown across the classroom for refusing to use Dark Magic.
From behind them another dementor came, and suddenly more appeared, sweeping towards them and surrounding them. "We know the spell," Rianna whispered, more to assure herself than anything. One of the dementors got up close to them, and they both heard their parents' cries of terror. "Expecto Patronum!" she yelled out breathlessly.
Silvery light spewed out of Rianna's wand, but was quickly extinguished by the Dark creatures. "Expecto… Patronum…," Martin repeated, but no light released from the tip of his wand.
And then one of the many dementors leapt in front of him. "Expecto Patronum!" Rianna managed to yell, but she couldn't make the light appear. Martin's back arched as the dementor fell forward, his skull inches from his head, getting even closer to his face in order to kiss him.
A dementor swept down next to Rianna, and tears stained her face. She thought of Martin, and how wonderful he's been to her. This can't be how it ends, she told herself, but apathy was setting in. She looked at Martin, his face vacant of expression. His mouth was opened slightly, and out from it came a small shining sphere of light. The dementor came still closer, wrapping his decaying teeth around Martin's soul, and Rianna felt something snap inside of her.
"Expecto…"
"Expecto Patronum!"
