High Magic

High arcana, or high magic, is an emerging magical field of study first discovered by a teldori archmage by the name of Lorin. Lorin theorized that due to the seemingly artificial nature of many of Arnen's features, coupled with the fact that ley lines were a wholly unnatural phenomena, that arcane magic was responsible for at least part of the creation of the world. That there must exist some form of 'high arcana' that as-of-yet was undiscovered. Many of his colleagues dismissed him out of hand, but his paper attracted the attention of one enterprising young mage by the name of Tyrania. Tyrania agreed with Lorin's findings, and requested apprenticeship from the archmage. Lorin accepted, and the two sat to work attempting to discover the "true nature of the Arcane".

Eventually Tyrania researched and developed the first High Arcana; Tyrania's Magnificent Dimension. She had learned how to use a derivative of Space magic to create a micro-universe. When she successfully crossed the Veil into the micro-universe, she was unfortunately never heard from again. Lorin continued the research despite the accident his star pupil had suffered.

Lorin went on to discover several new spells, all considered to be under the domain of High Arcana, or High Magic. Among them was the ability to open permanent portals between two locations without the use of a leygate. Others included the spell "Finger of Death", which materialized a bolt of red-lightning from the fingertips of its caster, capable of annihilating the target at a molecular level. Another spell, "Dark Portal" was devised, capable of opening rifts into random sections of the Prismatic Dark.

Lorin later theorized that High Magic could allow for its users to quite literally reshape worlds, create new planets, or even rewrite brain patterns with the wave of a hand.

Its existence is currently kept secret by the four great houses of Eldre'thas. The teldari continue to research and explore this new school of magic, weary of what could happen if knowledge of its existence were to get out.
