The barely breathing Crystal Dragon, Celine Delagrost, was placed at the eastern part of the square, two meters away from the area of the Water of Tranquility. The Undead Priest who took the mission was already standing in the faint white fog, concentrating to cast spells, his body emanating a golden glow... it was the glow of a large Divine Array.
Such a Divine Array is quite rare in Toril, where the energy concentration is much lower compared to Teraxil. If an array involving deities that can be activated by so many people appears, it's basically for offering sacrifices to the deities...it's more often used by followers of the Evil God.
In fact, when Hill discovered the situation here, he was also a bit skeptical. The Divine Array in Teraxil was probably learned from the Dwarves... just modified by some wise people.
