Clerics derive their ability to work miracles by utilizing the connection they share from another plane of existence. This connection is derived from an innate connection assumed to have formed at birth. Many people can go through life with the capacity to become a cleric, yet never fully realize. Those who hear the call of a distant realm and answer it are truly unique amongst society.
It is theorized that, though a cleric’s connection is innate, the ability to channel a pathway to another realm is not. All clerics everywhere seem to go through a right of passage by choosing a particular item to be a focus. This focus can take almost any physical form, an heirloom, a weapon, or even their favorite tankard. Usually the item itself holds great personal importance to the caster.
The connection to another realm is often described in terms of a calling. When a cleric realizes their connection, in almost all cases, their personality changes slightly. Many describe it as a religious experience to be able to feel the pull of another plane and dream of its varied landscapes. This has often given clerics the stigma of being pious and good natured, this is not always true. In fact, being religious has never been a requisite for clerics of our world. Some notable clerics have even been quoted as saying that god is dead and that the eternal soul is a lie.
