Because of the array formation that Kyran set up in his room, the noise and even the leakage of magic energy were contained inside. None of the Eidums passing by down the hall noticed anything strange. The only issue that arose was the Abbot's sudden disappearance again.
It was not that big an issue, though. Only, they wondered where he went without advising anyone. Kyran was one thing, but the Abbot rarely did that.
In any case, since Azikh and Gidan did not seem worried, none of the Eidums worried that much.
It took the Abbot and True Void around three days to stabilize Kyran's condition. If this happened in the Human plane, the Abbot would have collapsed before the second day ended because of the magic energy limitation of a human's magic core. One would not last more than a day, even more so three days, unless they had several high-grade energy-replenishing potions on hand.
