Squill, a male Pastorian, held the rank of colonel under the rule of King Siroc. He was the commander of an assault directed at a transport vessel carrying King's greatest adversary.
When Black Squadron from the Resistance landed on Pastoria seeking assistance from King Siroc, the king opted to present them to Colonel Squill instead. Squill was tasked with leading a transport through an area that Siroc described as being controlled by terrorists. Siroc then asked the squadron to protect the transport, a request they accepted.
During the escort of the transport through the designated zone, a group of starships linked to Siroc's main competitor for the throne responded with force, as they thought Siroc was invading them. Temmin Wexley, known as Black Leader, inquired of Squill about the actions of the other ships. Squill responded by announcing that they were under attack and commanded his starfighters to safeguard the transport. Following a short battle, the opposing forces started to withdraw, but Squill and his troops persisted in their attack, ultimately obliterating their transport and eliminating Siroc's rival.
