Bìth Sgàthan is a form of Ebon Mysticism that studies the metaphysical building blocks of the universe. The pure form of this mystery school has been lost to the ages, what remains (in secret) is a school of heretic mysticism that is based on a twisted form of the original thoughts. This school was openly hostile towards SLA Industries; they declared that SLA Industries and Mr. Slayer were the Defiler of the ancient Ebon prophecies and further proclaimed that Ebons being a part of the World of Progress was a corruption of the natural order, an abomination. According to SLA historians the leaders of this sect (that nowadays is known as the Bìth Sgàthan; the fact that this is only the twisted form of true Bìth Sgàthan is unknown), among them the semi-mythic Ineashon, even planned an armed secession if their plans had come to frutition. However, their plans were discovered (through treason some claim) and the sect was destroyed. Still the knowledge continued to exist and young, inquisitive Ebons can quickly fall under the spell of it's promising lure.

The original philosophy of Bìth Sgàthan is based on Fhuair, the Lore of Emanation, stating that the universe was formed in several stages. Each of these stages manifests through the creation of a metaphysical sphere, an "Emanation".

"The first Emanations is the Vortex; the Creator created chaos in order for the universe to create itself and thus arose Cruitheachd, the Endless Possibility. Out of Cruitheachd sprang the Flood of Thought, creating the universal spirit. Thus the universe achieved self-consciousness and the second Emanation was formed, called Spairn. By fuelling the possibilities, patterns arose, giving Form to the universe, which was mirrored in the third Emanation, Cumadh, the Form of Thought. And out of these Forms of Thought arose conflict.

And still, the energy of creation spew out countless new patterns into the universe, each prolonging the conflict so that it seemed eternal. Out of this eternal cycle of creation, conflict and destruction of new forms arose the fourth Emanation, called Amannan or the Endless Time. And as the cycle went on, and new patterns were created, and older were destroyed, the fifth Emanation, Falamh, rose out of this destruction, collapsing the destroyed patterns and filling them with emptiness. Now the universe was roughly formed, and it existed in an endless cycle of creation, conflict and rebirth, which in itself became a pattern and out of it arose the sixth Emanation, Siorruidh, or the Singularity of Stasis.

Thus the universe was shaped roughly linearly, but still lacked any shape at its centre. Due to the duality of the universal conflict two universal poles manifested: the Line of Light and Day and the Line of Dark and Night. They became the seventh and eighth Emanation. Crannag, the Line of Light provided strength and life, while Sgìth, the Line of Dark, presided over the Final Dissolution of Decay, providing the gate through which all structure is destroyed.

The Cairt is an ancient deck of cards that has been constructed with the Pattern of Being (Samhladh) and the Lore of Emanation (Fhuair) in mind. The Cairt are an interpretation of the Lore of Emanation, using the principles put forth in this philosophy to create a deck of cards that is said to mirror the forces of the universe and with which the initiate is able to tap into the forces of the universe, divining the future and possibly influencing it by using the cards in a special arcane ritual.

A traditional full deck consists of 63 cards, 36 of them look like usual Ebon playing cards, consisting of three suits á 12 cards, mirroring the three worlds of Kavella: Anmoch, or the World of Night, Mochthrath, or the World of Day and Còmraig, or the World of Conflict. However, modern decks lack these 36 so called "World" cards, since they are considered minor cards and are not mirrored in the Samhladh.

Instead, modern decks emphasise the importance of the pure Samhladh and only include the 9 Great Cards, which correspond to the 9 Emanations and the 18 Way Cards, which symbolize the 18 Ways between the Emanations on the Samhladh.

For a divination the cards are shuffled and nine cards are selected. These cards are then dealt in a pattern that corresponds to the positions of the Emanations on the Samhladh. The first card stands for the current situation, the matter at hand. The second card stands for what the querant consciously thinks about the matter at hand. The third card represents the querant's subconscious thoughts about the matter, the foundation of the situation. The fourth card represents the immediate past and gives insights into the cause of the current situation. The fifth card represents the immediate future, what will happen next. The sixth card represents the querant and his thoughts about the matter or how he feels about it. The seventh card shows his surroundings; this can be an actual place or the influence of others on the situation. The eigth card symbolizes the querant's hopes and fears; it has no divinatory function, instead it gives insights into the motivation of the querant. The ninth and last card finally shows the final outcome, the ultimate climax, the overall general direction that the situation will evolve into.

Reversed Cards are treated specially in the divination. Instead of their face value, they are treated as if their value was mirrored on the Samhladh. Thus a reversed "Kilneck" card would be read as if it was a "Necanthrope" card; a "Mariner" would be read as a "Wanderer" or a "Cararact" as a "Ferryman". Because of this, reversed cards are commonly called mirrored cards. For the divination they are indicators for a treacherous situation, an event that appears as something specific at face value (the original meaning of the card), but actually is something completely different (the mirrored meaning of the card). The mirror pairs are:
