Passage: Olvir Hnufa or Ölvir hnúfa was a Norwegian commander in a clan and poet of the late ninth and early tenth centuries, known from, among other sources, Egil's Saga, Skaldatal and the Prose Edda. Olvir was the son of the viking Berle-Kari and brother-in-law of Kveldulf Bjalfason, who married Olvir's sister Salbjorg Karadottir; he was thus uncle to Skallagrim and Thorolf Kveldulfsson and great uncle to the famous poet Egil Skallagrimsson. Olvir also had a brother named Eyvind Lambi. Olvir was a prominent member of the court of King Harald Fairhair, who united Norway under his rule in the late ninth or early tenth century. Among other famous poets, he served as one of King Harald's court poets. He also served as a warrior in Harald's retinue, and fought at the pivotal Battle of Hafrsfjord on the king's flagship. He is best known for his involvement in the conflict between Harald and Olvir's kinsman Thorolf Kveldulfsson, which ended with the latter's death. Only a few fragments of Olvir's poetry survive.

Passage: Thomas Stephen Kenan (February 12, 1838 – December 23, 1911) was a Confederate soldier, and later a politician. His parents were Sarah Rebecca Graham and Owen Rand Kenan; he was the grandson of U.S. Congressman Thomas Kenan and great-grandson of Revolutionary War general James Kenan. He started his education in Duplin County, North Carolina at Old Grove Academy in Kenansville (the town was named for his great-grandfather in 1818). Later he spent a year at Central Military Institute in Selma, Alabama. Thomas spent his freshman year of college at Wake Forest in June. Thomas then transferred his sophomore year to the University of North Carolina, where he would graduate in 1857. He studied law for two years with Judge Pearson at Richmond Hill where he practiced law in Kenansville. After graduation and during the Civil War he became Captain of the Duplin Rifles in the Confederate States Army, elected lieutenant colonel of the 43rd North Carolina Infantry Regiment in April 1862, and was promoted to colonel later that year. He was wounded at the Battle of Gettysburg. While on an ambulance train, he and his older brother James Kenan were both captured; they were then imprisoned on Johnson's Island, Ohio. On March 22, 1865, he was released on parole but never switched sides during the war. On his return home he was elected to the state legislature from 1865 to 1867. Later that year he ran for Congress and lost. Not letting that defeat end his political career, he moved to Wilson, North Carolina, where he became mayor and was elected North Carolina Attorney General, serving from 1877 to 1885. In May 1868 he married Miss Sallie Dortch, but they had no children; Sallie died in 1916.

Passage: Extremely Severe Cyclonic Storm Chapala (, iiesar tashabalaan; ) was a powerful tropical cyclone which caused moderate damage in Yemen during November 2015. The third named storm of the 2015 North Indian Ocean cyclone season, it developed on 28 October off western India from the monsoon trough. Fueled by record warm water temperatures, the system quickly intensified and was named Chapala by the India Meteorological Department (IMD). By 30 October, the storm developed an eye in the center of a well-defined circular area of deep convection. That day, the IMD estimated peak three-minute sustained winds of 215 km/h (130 mph), and the JTWC estimated one-minute winds of 240 km/h (150 mph); only Cyclone Gonu in 2007 and Cyclone Kyarr in 2019 was stronger in the Arabian Sea.
