Rockwell is the explorer from the notes. He gained trust with Helena, but soon felt betrayed when she helped someone else. He soon became evil and stopped several survivors from respawning. He always mocked them everytime he beated the HLN. Soon, he found a person to find element for him. And like other people say now, with the element he injected himself, turning into this beast. His role in the ark story is the antagonist.
