Markus moved a little back as I prepared myself to absorb the surrounding mana.
I was planning to try supplying my own mana first to see what happens, and based on the outcome, I could decide whether I should use the surrounding mana or not.
Since the door was already within some kind of barrier, I touched the ground and slowly supplied mana towards the manor. As I was doing that, I realized this whole process was more delicate than I thought. I needed a lot more focus, so I closed my eyes and focused only on the supply of mana.
When my mana reached the door, I could visualize the seal in my head. It was some sort of ancient three-dimensional seal that occupied the whole manor.
