RWBY: First Contact
You are, all of you, vermin. Cowering in the dirt, thinking... what, I wonder? That you might escape the coming fire? No. Your world will burn until its surface is but glass! And not even your Demon will live to creep, blackened, from its hole to mar the reflection of our passage; the culmination of our Journey. For your destruction is the will of the gods! And I...I am their instrument!
(Just a disclaimer I didn't create RWBY or Halo)
