While the idea of setting the crystals off was simple, Eldrian did not know how to manage this.
He had barely managed to take a peek at what they held inside them. His meager magic would not be able to destabilize the crystals. These were not simple mana crystals that he could easily make unstable.
Heck, the voidstone was still stable even though it was but a fragment from the device that the alicorns had used. Eldrian had even failed to take a glance at what it held.
To make matters worse, even in the heightened state that Eldrian was thinking and observing things in, he knew he did not have long. He could see the lighting already gathering around Zaphreal's hand.
Void of an alternative, Eldrian picked the crystal he had first managed to force his will inside. Assuming it was the least stable.
Hope you all enjoyed, and I'll admit I enjoyed the day off.
Tried not to think of ANW so I could get a fresh perspective. I do hope this will allow me to better the pacing of the story.
