Forming a perfect circle which had three concentric stars in it and a small circle in the middle, the activated ritual rune first brought intense lighting to the battlefield, making some of the soldiers who had been peeved at having to fight at night let out sighs of relief but then it didn't last long.
Though most were slow to pick up on it, the soldiers from the underworld included, within seconds, it didn't take them long to realise that the battlefield was being rapidly saturated with mana, one that was very foreign to the soldiers who were defending their home country and very surprising to the soldiers from the underworld considering such mana should only exist in the underworld.
