Question: How long had Prüm Abbey existed when Eygilo left to become the abbot of Flavigny? Passage:The fame of Flavigny was due partly to the relics which it preserved, and partly to the piety of its monks. The monastery was at the height of its reputation in the eighth century, in the time of the Abbot Manasses, who was appointed by Pippin the Short. In 760/62, Manasses attended the council of Attigny. Pippin's successor, Charlemagne, authorized Manasses to found the Carolingian style monastery of Corbigny. The same Manasses transferred from Volvic to Flavigny the relics of Saint Praejectus. Abbot Apollinaris, appointed by Charlemagne in 802, was also abbot of Saint-Bénigne de Dijon and Môutier-Saint-Jean. Charlemagne's son, Louis the Pious, used Abbot Adrevaldus as an envoy to Septimania in 834 and 838, according to the Historia Hludowici imperatoris. However, these dates do not correspond to those given in the abbey's only list, which says that Adrevaldus became abbot in 839 and ruled for three years. Eygilo, the founder of Prüm Abbey, left his own establishment to become abbot of Flavigny in 860. He set up monks at Corbigny, but later left Flavigny when he was appointed Archbishop of Sens. His successor, Geylo, resigned to become abbot of Tournus and was later appointed bishop of Langres.

Question: Who is the oldest person recruited to join Demon Hunter? Passage:In 2003 they took a short break, during which McCaddon decided to leave Society's Finest, and went on to join Demon Hunter. After leaving Society's Finest and Embodyment, Ryan Clark and Don Clark, formerly of Training for Utopia, recruited him, Jesse Sprinkle, formerly of Poor Old Lu, and Jon Dunn (Who would later join Soul Embraced) to join their project, Demon Hunter. Demon Hunter already had an album before he joined. On this album McCaddon had contributed by photography. On his Demon Hunter debut, Summer of Darkness, was great success. In 2005, Ethan Luck, formerly of The O.C. Supertones and Project 86, replaced McCaddon. In 2006, former Embodyment members, Mark Garza (drums) and Andrew Godwin (guitar), contacted McCaddon and said they wanted to play metal again. McCaddon contacted former Society's Finest member, Nick Nowell (bass) and asked him to join their new project, The Famine. Though McCaddon knew people would compare the Famine to Embodyment, he stated that "We started The Famine because we wanted to get away from the stuff we were playing with Embodyment...".
