Question: How long had Blue Byte been in business as game developer when their game, The Settlers: Rise of an Empire, was published by Ubisoft? Passage 1:Mimas Peak () is a sharp conspicuous peak, rising to about west of the head of Saturn Glacier and west of the Dione Nunataks in the southeast part of Alexander Island, Antarctica. It was first seen and photographed from the air by Lincoln Ellsworth on November 23, 1935, and mapped from these photos by W.L.G. Joerg. The peak was sighted from a distance in 1949 by the Falkland Islands Dependencies Survey (FIDS) and roughly positioned. It was named by the UK Antarctic Place-Names Committee for its association with nearby Saturn Glacier, Mimas being one of the satellites of the planet Saturn. The peak and surrounding area were first mapped in detail from air photos taken by the Ronne Antarctic Research Expedition 1947–48, by D. Searle of the FIDS in 1960.
 Passage 2:The Settlers: Rise of an Empire () is a city-building game with real-time strategy elements, developed by Blue Byte and published by Ubisoft. Released for Microsoft Windows in September 2007, it is the seventh game in The Settlers series. In March 2008, Blue Byte released an expansion, The Settlers: Rise of an Empire - The Eastern Realm (), featuring new single-player campaign missions, new maps for both single-player and multiplayer modes, and an enhanced map editor. In September, they released The Settlers: Rise of an Empire - Gold Edition, containing the original game plus the Eastern Realm expansion, and additional single and multiplayer maps. The Gold Edition was also released on Steam and Uplay. In 2015, it was released on GOG.com, and in 2018, it was re-released as The Settlers: Rise of an Empire - History Edition.
 Passage 3:After the fall of the Lovell family following their support of the Lancastrian cause during the Wars of the Roses, the castle was confiscated in 1461 and passed through several owners until bought by Sir Thomas Arundell of Lanherne in 1544. The Arundells were an ancient and prominent Cornish family, the principal branches of which were seated at the manors of Lanherne, Trerice, Tolverne and Menadarva in Cornwall. The family held several estates in Wiltshire. The castle was confiscated when Sir Thomas — a staunch Roman Catholic — was executed for treason in 1552, but in 1570 was bought back by his son, Sir Matthew Arundell, later a Sheriff and Custos Rotulorum of Dorset. The Arundells, led by Thomas Arundell, 1st Baron Arundell of Wardour, subsequently became known as some of the most active of the Catholic landowners in England at the time of the Reformation; thus they were naturally Royalists in the English Civil War. During that conflict, Thomas Arundell, 2nd Baron Arundell of Wardour, was away from home on the King's business and had asked his wife, Lady Blanche Arundell, aged 61, to defend the castle with a garrison of 25 trained fighting men. On 2 May 1643 Sir Edward Hungerford, with 1,300 men of the Parliamentarian Army, demanded admittance to search for Royalists. He was refused and laid siege, setting about the walls with guns and mines. After five days the castle was threatened with complete destruction. Lady Arundell agreed to surrender, and the castle was placed under the command of Colonel Edmund Ludlow. Lord Arundell had died of his wounds after the Battle of Stratton, and his son, Henry 3rd Lord Arundell, next laid siege to his own castle, blew up much of it and obliged the Parliamentary garrison to surrender in March 1644.
