Rem attended Prince Tiberias Calore VII's Queenstrial along with his family, and the other High Houses. His daughter, Rohr Rhambos, was the first contestant to participate, using her strength to pulverize the statues in the arena.
In the aftermath of King Tiberias Calore VI's assassination, one of Rem's sons, Ryker Rhambos, was one of Mare and Cal's chosen executioners, alongside Evangeline, Ptolemus Samos, Stralian Haven and Lord Osanos.
Cal led the Guard and Montfort forces on an assault of Harbor Bay to seize the city and the region from Maven's control and establish a temporary capital. After a difficult struggle, the city was captured.
Rem was brought before Cal and Dowager Queen Anabel Lerolan. On his knees before the true king, Rem officially surrendered the city and quickly acquiesced to Anabel's order to address Cal as the king. Without hesitation, Rem gives control of the city of Harbor Bay, and the entirety of the Beacon region, to the true king of Norta. When asked by Cal about his House, Rem confirmed they were loyal to him as well. Rem, fearing Cal would have his entire family executed, asserts his soldiers, money, and resources were all at his disposal, proving how useful his House could be if left unscathed.
Cal accepts Rem's surrender and oath of loyalty, with the clear understanding that every member of his House will do the same, forsaking the false king Maven. Rem agrees to arrange this by tomorrow, and shouts out his loyalty to the rightful King of Norta. He is then dismissed from the room.
Maven is later surprised to learn of Rem's actions in a message from Cal, asking for a summit to discuss terms of surrender. Maven was angered and called Rem a traitor.
Rem and his House are present when Cal is crowned King of Norta.
Lord Rhambos is a cruel man. Ada Wallace, who worked as a housemaid in his Harbor Bay mansion, remarks that Rem likes to hunt. Although she says that what he does with the animals he hunts on his estate can't actually be called hunting because the animals are put in a pit. Then Rem and his sons, Ryker and Rydal, fight them and break their necks for sport.
Lord Rhambos had no sympathy for the Dagger Legion, the legion of fifteen to eighteen year-old Reds conscripted under the Measures. He mockingly called the Little Legion and was unbothered by their imminent slaughter.
He is described as a "mountainous man," with a strongarm's bulky physique. He has dirty blond hair, giving over to gray, which is braided back from his face in intricate rows. He wears robes resplendent in rich chocolate and crimson edged with previous stones.
Rem, like all members of House Rhambos, is a strongarm. His ability makes him stronger and more physically durable than humans.
