SIDH or the Other World in the Celtic civilisation is a place out of time, space and human suffering.
This "paradise" means also "peace" in old Irish.
Concerning the Banshees, they are the messengers of the Other World, hiding under the Sidh, these mounds built by the ancient Irish Gods with the arrival of the Firt Men.
They are known for the horrible scream they cry out at night on the desolated moors, and announcing his imminent death to anyone who has the misfortune to hear it.
From "the Roots of Enchantment" rise another universe, more peaceful, more luminous, which is not without causing some thinking on our world, and even carry a little hope.
