Prophets and Locust

This is my admission to the sci-fi contest on web-toons. It's the story of a possible future in aliens disclose their existence to the world. As World leaders, governments and religions debate the agenda of the extraterrestrials known as Ascended Brethren, a swarm malevelent beings come to consume mankind like locust. Are the Brethren who they say they are, or they something far more sinister?
