Protonymics and neonymics, often simply called nymics, make up an entity's incantory name—sometimes referred to as a true name. They are employed as the focus for incantory magic, allowing the user to gain substantial control over whom the Nymic belongs to, typically by summoning or banishment. However, if the entity possesses both a protonymic and a neonymic, speaking only one of them bears little to no effect.
The invocation of an immortal Daedra's true name drains its "vital force" into Oblivion, which forces the entity to follow. It remains there until its vital force replenishes itself, a state which is described as "somewhat analogous to sleep for mortals". But as Daedra do not require sleep, it is viewed by them as a state "as close to the terror and despair of death" as they can experience.
One historical usage of an 'incantory name' was in the banishment of the Daedric Prince Mehrunes Dagon by an apprentice during the invasion of the Battlespire in 3E 398. The sorcerer Chimere Graegyn had previously invoked the Prince's protonymic at some point before 3E 172; over two hundred years prior. Lord Dagon's full incantory name (as recorded) is Lehkelogah, Djehkeleho-dehbe-effehezepeh. In addition to this, the Apprentice used the neonymics of three Daedra Lords, all of which were recorded within the notes of Dagon's lieutenant, Grand Vizier Imago Storm.
- The term nymic-path is referenced within Commentaries on the Mysterium Xarxes, Book 3, but its meaning is unknown.
- Daedric clans are known to have protracted tribunymics which are never spoken or revealed lest they be used as a weapon against them.
- Another related term is paleonymic, a name which can be used to bind a Daedra.[UOL 1]
- Hieronymics are the classifications that Daedra use for each other, though they are supposedly outside of mortal understanding.
- Harmonic Astronymics is an ancient Dwemer text which seemingly deals with the constellations and how to harness their power.
- The term chrononymic is used in association with Sotha Sil (such as 'chrononymic will'). It also appears to be used in the context of Sotha Sil banishing Mehrunes Dagon.
