They are avatars of various elements and energies, and they inhabit all realms. They do as they will and seldom concern themselves with humankind or Fae unless summoned. If asked for help, they often exact steep prices in return. The Elemental Lords are not concerned with balance like the Hags of Fate.

FBH: Full-Blooded Human (usually refers to Earthside humans).

FH-CSI: The Faerie-Human Crime Scene Investigation team. The brainchild of Detective Chase Johnson, it was first formed as a collaboration between the OIA and the Seattle police department.

Great Divide: A time of immense turmoil when the Elemental Lords and some of the High Court of Fae decided to rip apart the worlds. Until then, the Fae existed primarily on Earth, their lives and worlds mingling with those of humans. The Great Divide tore everything asunder, splitting off another dimension, which became Otherworld. At that time, the Twin Courts of Fae were disbanded and their queens stripped of power. This was the time during which the Spirit Seal was formed and broken in order to seal off the realms from each other. Some Fae chose to stay Earthside, others moved to the realm of Otherworld, and the demons were—for the most part—sealed in the Subterranean Realms.

Hags of Fates: The women of destiny who keep the balance righted. Neither good nor evil, they observe the flow of destiny. When events get too far out of balance, they step in and take action, usually using humans, Fae, Supes, and other creatures as pawns to bring the path of destiny back into line.

Ionyc Lands: The astral, etheric, and spirit realms, along with several other lesser-known noncorporeal dimensions, form the Ionyc Lands.

Portal, Portals: The interdimensional gates that connect the different realms. Some were created during the Great Divide; others open up randomly.

Seelie Court: The Earthside Fae Court of Light and Summer, disbanded during the Great Divide. Titania was the Seelie Queen.

Soul Statues: In Otherworld, small figurines created for the Fae of certain races and magically linked with the baby. These figurines reside in family shrines and when one of the Fae dies, their soul statue shatters. In Menolly’s case, when she was reborn as a vampire, her soul statue re-formed, although twisted. If a family member disappears, his or her family can always tell if their loved one is alive or dead if they have access to the soul statue.

Spirit Seals: A magical crystal artifact, the Spirit Seal was created during the Great Divide. When the portals were sealed, the Spirit Seal was broken into nine gems and each piece was given to an Elemental Lord or Lady. These gems each have varying powers. Even possessing one of the spirit seals can allow the wielder to weaken the portals that divide Otherworld, Earthside, and the Subterranean Realms. If the all of the seals are joined together again, then all of the portals will open.

Stradolan: A being who can walk between worlds, who can walk through the shadows, using them as a method of transportation.

The civil war has ended and Tanaquar is restoring order to the land.

Youkai: Loosely (very loosely) translated as Japanese demon/nature spirit. For the purposes of this series, the youkai have three shapes: the animal, the human form, and the true demon form. Unlike the demons of the Subterranean Realms, youkai are not necessarily evil by nature.
