Sojourner

Sojourner is the son of Spectre and father of Thunderhawk. As a member of the Brotherhood of Guardians following his tenure as Guardian of Angel Island, he has fought many times against the Dark Legion during Knuckles' time in the position. Following Dr. Eggman Robotnik's greatest offensive against the island, in which Sojourner battled alongside several other members of the Brotherhood to defend the Master Emerald, he was studied by Dr. Finitevus and then banished to the Twilight Zone.

Member of the Brotherhood
Like his son Thunderhawk, little is known about Sojourner's tenor as Guardian of the Floating Island. As a member of the Brotherhood however, Sojourner contributed to protecting the Echidna's interests on a global scale. When the Brotherhood was discussing the carnage around Mobius following Sonic the Hedgehog's chase of Ixis Naugus, Sojourner was about to mention the area he was watching over before being interrupted by Sabre.

The Queen Alicia Incident
During the Great War, Queen Alicia Acorn and her infant son Elias were sent to Angel Island to avoid being captured by the invading Overlander hordes. As their ship approached the island however it was shot down by aerial Overlander ships. After it crashed, the Brotherhood arrived on the scene first. Sojourner discovered amongst the wreckage the baby Elias. Sabre, who was in charge of the mission, told the arriving Overlanders everyone had died in the crash. Following the Overlander withdrawal from the island, the Brotherhood took Alicia and Elias to the safety of Haven where the dying queen was put into cryo-sleep.

When the issue came up over whether to inform King Max of his wife and son's survival, Sojourner decided it was best to keep it a secret for the time being, stating "If the Overlanders discover we withheld the facts from them, that will force their hand into taking action, upon which we would be forced into taking action, and getting dragged into a war we have no interest in whatsoever". Thus, for the next several years, the Brotherhood raised Elias, with Sojourner actively teaching him and acting as a father figure. When Elias was old enough, the Brotherhood left him in the care of Colonel Sommersby at the Royal Compound.

Fighting the Dark Legion
During the Dark Legion's attempt at rigging the Echidnaopolis elections, a task force was dispatched to take over Haven. Due to its defences being sabotaged by Moritori Rex during his impersonation as Tobor, Sojourner, Thunderhawk and Sabre were completely caught off guard and captured by the Dark Legion. However, the three were rescued by Locke and Spectre.

Following the return of Mathias, Sojourner participated on the Brotherhood attack on the Grand Conservatory to put an end to the Dark Legion's attempted takeover of the Floating Island. However, he along with the other Brotherhood members were caught in a trap and banished to an alternate zone when the Dark Legion Battle Cruiser fired the Quantum Beam. Sojourner and the rest of the Brotherhood were returned to Mobius when Chaos Knuckles undid the effects of the Quantum Beam. When the Brotherhood rummaged through the ruins of Haven, Sojourner believed there to be evidence as to who was behind its destruction. His son Thunderhawk soon pointed out that it was obviously the Dark Legion.

Last Stance and Captivity
During Sonic's year long absence, the Eggman Empire launched a full-scale offensive against Angel Island with assistance from the Dingoes, who allied with Eggman in exchange for technological and military assistance. During their invasion, Sojourner along with the rest of the Brotherhood defended the Master Emerald from being captured. The battle drained them of most of their energy, and they were believed to have been killed in the fight.

Having been badly weakened from their battle with Eggman's forces, Dr. Finitevus had no problems holding the Brotherhood captive. From there, Finitevus performed numerous studies on each member of the Brotherhood in order to understand their relationship with Chaos energies. Once he felt he learned all he could, Finitevus dumped the Brotherhood and Moritori Rex into the Twilight Zone, leaving them for death.

Personality
Sojourner was known for stating his mind. When the issue came up over the Brotherhood's use of excessive technology despite the Echidna's ban of it, Sojourner was quick to mention that the Brotherhood were hypocrites. Sabre disagreed, stating that their technology simply allowed them an "even playing field" with the Dark Legion, and that the technolgy was not meant to be banned forever. Sojourner replied saying there was no proof that their ancestors meant for technology to come back, but before the debate could finish, he, Sabre and Thunderhawk were captured by Dark Legionnaires. Sojourner seemed to have the least amount of discontent for the Dark Legion amongst the Brotherhood members.
