Context_1 : Villain was a wooden roller coaster at the Geauga Lake amusement park in Aurora, Ohio. It was designed by the now-defunct Custom Coasters International (CCI). The ride opened as a part of the four-coaster expansion Six Flags brought to Geauga Lake between 1999 and 2000. It was a wooden hybrid, which means it had steel supports but had wood track. When it originally opened, the ride was moderately smooth, but by 2001 it deteriorated and was re-tracked during the off-season. This was the second CCI coaster to feature a "trick track" element (the first was Shivering Timbers at Michigan's Adventure) which the track banks from one side to another while staying otherwise on a straight path. Context_2 : Aurora is the former train station serving the residents of Aurora, Ohio, located within Portage County, Ohio, USA. The station was constructed in 1872 by the New York, Pennsylvania and Ohio Railroad, which had absorbed the former Cleveland and Mahoning Valley Railroad, which ran from Cleveland, Ohio to Leavittsburg, Ohio. The next station to the northwest was Geauga Lake, serving the Geauga Lake amusement park. The next station to the southeast was Mantua. The line was entirely acquired by the Erie Railroad in 1941 after dissolution of the New York, Pennsylvania and Ohio. The last train left Aurora station on January 14, 1977. After the line was abandoned, the rails were taken up. The station depot, one of three still standing along the branch (along with Solon and Mantua), was listed in the National Register of Historic Places on May 22, 1986. Context_3 : Geauga Lake is an abandoned theme park in Bainbridge Township and Aurora, Ohio, United States. Established in 1887 in what had been a local recreation area adjacent to a lake of the same name, the first amusement ride was added in 1889, and the park's first roller coaster – later known as the Big Dipper – was built in 1925. In 1969, the park was sold to Funtime, Inc., and was expanded over the years with additional rides and amenities. Further expansion occurred in the mid and late 1990s after Funtime's acquisition by Premier Parks in 1995. Prior to the 2000 season, soon after Premier Parks acquired Six Flags, the park was re-branded as Six Flags Ohio and four new roller coasters were added. A year later, Six Flags bought the adjacent SeaWorld Ohio and combined the two parks under the name Six Flags Worlds of Adventure.
