Disturbing Conclusions

If my calculations are correct--and unless Athalor deliberately sabotaged me I know they're correct--something is seriously wrong with Ioth Academy. This is not a new development, it's a process that must have been going on for years. I haven't shared my concerns with anyone but Garnet yet...but this may the exact task the Codex is suited for.
 
To put it in terms anyone could understand, the academy is built on a naturally occurring reserve of Dawn Energy stabilized and expanded by Ioth and his companions and anchored by the Spire to create a cohesive zone in which ambient arcane pulses facilitate the continued endurance of normally fleeting spell matrices. The lodges, the ring, the planar metageometric properties of the space within the sphere, the defensive and climate changes enacted by the sphere itself are all the result of stable Dawn Magic. That magic should be rotating in concentric fields, some clockwise, some counterclockwise, around the spire as part of the stable pattern.
 
What I've found is that there's a negative force, a vacuum or friction of some kind, impeding that rotation, drawing Dawn Energy back into itself. This drainage accounts for the semipermeable barriers between the extraplanar space denoted by the Sphere and the Otherworld, thereby causing the fey incursions that have plagued the school since at least I began attendance.
 
The problem is, I can't think of who would be capable of this. It could be a flaw of some kind...but I'm sure Ioth wouldn't leave a flaw and would notice it immediately?
 
Could something have happened to the progenitor of all magic? There's no way he's actually behind this.
 
If the Codex is to preserve the legacy of Ioth and his companions and the magical traditions of the Alfar, solving this crisis is our most important purpose. It's what's going to set us apart in history as the Best of the Best.
