Team RWBY was sitting in their dorm when Ozpin messaged Ruby saying 'you girls need to go to a weird ring like planet meet outside now'
"Guys we have a mission" said Ruby
"What is it?" asked Weiss
"We have to go to a ring like planet"
"WHAT!?" they said in sync
"Sis do we have to go?" Asked Angel
"Yes sis i dont want to go" said Sapphire
"Yep we have to"
"When do we have to go?" asked Yang
"Now" with that they left the room with their weapons and walked outside,when they got outside they saw a ship that said UNSC and it looked like a bird
"Are we going in that,is it safe?" said Weiss
"Yes It looks like a deathtrap" said Grey
"Yes it is safe" said Ozpin they get in and the ship takes off
"my name is echo 419 I am sending you to a ship called the pillar of Autumn"
"What is that?" asked Ruby looking
"Halo" Ruby messages Ozpin 'how did you get in touch with the UNSC' he messages back 'I used to be an admiral with the UNSC' they feel the ship land and they get out
"So you team RWBY?" said a voice
"Who are you if you don't mind me asking?" said Blake
"I'm captain keyes I am the captain of the pillar of Autumn"
