In the eternal forest where the elves live, a sudden massive burst of mana started to envelop and encroach the whole forest. If that wasn't bad enough after the massive burst of mana came a blood-curdling killing intent. The killing intent was so terrifying it made even the bravest weak in the knees.
Those that were farther away from the source of the mana burst and killing intent were less affected and only felt a bit dizzy. The unlucky ones who were near the source were the elders and the elite guard. They were able to withstand the pressure but it was taking everything they got to remain conscious. Some of the weaker ones even started puking and crying.
