This magic has been pulled from lore in order to be rewritten. As such, it is now to be treated as an Unwritten Magic. What this means is that you cannot use this magic IC, cannot progress it in skills or knowledges. Any previous skill points or knowledges will remain and be grandfathered in. This decision came from Basilisk, Developer Team Lead, at the recommendation of Aegis, Lore Analysis Team Lead.
Basilisk and Pegasus are currently working on the rewrite, so any further questions may be directed to them.
