Religion of the Aerican Empire: 'At its most basic level, Silinism is the worship of Forsteri, the Great Penguin. Because of its disorganized nature and the iconoclastic nature of most of its adherents, the exact nature of Silinism varies widely between faithful, but the basic tenet of the belief in Forsteri remains. Over the years, less religiously-minded faithful have moved away from worship and turned instead to a more spiritualist and philosophical practice, which has become known as the Path of Forsteri.'
I feel the necessity to note that Silinism is not a national religion of Aerica, merely a widely-practiced one. The religion is also not limited to the Empire. I personally know a non-Aerican who is a Silinist.
