You scout them

You watch the elves taking food from a housing tent. You also saw the elves had tall towers watching over many miles. You knew they probably will see you coming when you attack. You could use that to your advantage.

The elves walk around in mostly cheerful tones not knowing a huge attack were coming for them. The largest tent must hold the elf queen and her generals. You saw a lone elf man going into a lone tent.

You took this as motivation to make your move. You stalk your way up to the tent and saw that he were washing robes of different shapes and sizes. You pull the dagger from your waist bend and slit his throat. You held his throat with both hands making sure his blood didn't spill. You then cover his body with half of the clothes that was in here.

You threw a robe into your bag and begin to sneaky walk back to the forest. As you walk into the forest a tall dark figure grab your shoulder forcing you to stare at him. You look at his facial features seeing a white scar going from the left side of his hairline to the bottom of his cheek.

"John don't do this. She tempted you to the wrong side. Comeback to the right side and help us put the world back to the peaceful world that we all know."

"Who are you?" you ask but knowing before he any said anything.

"One of the fives. So will you help us defeat Yoeisa and the humans." he said to you.
