Life Force.

Valerian sat at the back of the pond and asked, "Your Excellency, how do I even extract a drop of water from this pond? It is not budging." 

He had been trying for half an hour, but none of the methods worked. His hand wouldn't get wet even if he soaked it in the water. Neither did it move with mana. Valerian had no other option but to ask. 

Boo-too nodded and said, "It is the life force of a Mother. You do not take such things. You ask for them. Close your eyes and convey your intentions to the pond. It will answer." 

Valerian closed his eyes and joined his hands in prayer. He prayed for the pond to grant him a drop of water. He sat in such a position for a few minutes before the pond rippled. Wisps of mist over the pond swirled and condensed into a drop of water. Valerian sensed the process and opened his eyes to find the drop slowly moving toward him.
