Drawing arrays and planting seeds… The meaning was clear for Ed but to the elves this was an entirely foreign concept. The legacy of the elven arrays had been lost to its totality.
Ed could be certain of this, when he infiltrated the old elven underground village he saw no trace of any arrays. The closest thing to an array that might have been in the village were the earthen mages that sealed and opened its entrance but… That was the work of mages not an array.
'When I think about it, I suppose it makes sense that there are no arrays' Without any magic crystals to be found in the arid and abandoned desert, there was nothing to reliably use as power for the arrays.
The elves could have used elves for the task but what's the difference between just having the earthen mages do the job themselves at that point?
