Cid Warlock is a human spy and one of the strongest sentinels in the human race. Sentinel Cid worked in the field to keep an eye out for any extraterrestrial cultures that would pose a threat to humanity, in contrast to the Marshal, who remained in the Human Star to defend their territory from intruders. Among their opponents is the Planet Hive insect race. Ultimately, hundreds of years ago, the former Marshal had murdered the Zerg Emperor and Zerg Empress.
Cid Warlock skirted the guards at the door and crept into the King's Chamber. However, not a single person was present within the palace, not even a female zerg servant who was waiting. It is obvious that King Augustus Kaiser was among the first to mistreat and denigrate female zergs, which is why he was able to obtain information from them with ease. Even so, once they invaded this planet in order to exterminate the enemy, they would all still die.
