Just nearing the ruin where the potential bridge to the elemental planes had been found, Onyx and Rise sensed something strange. It was better to describe what they felt was like something slipping through their fingers than just mana leaking.
The feeling that the light mana had hit a wall and was slowly slipping through rather than being held back was a better way to describe what was going on in this situation. Especially since when they tried to pull at the light mana, they found that they could not force it to move any faster. Nor could they push the light mana to stop flowing either.
"It is under some sort of pressure?" This was an odd feeling. Onyx had never sensed something like this. He had never felt that the light mana was under pressure.
