I'm walking to the room where Veritus kept the Black Python's egg. He kept it in a special room for me to take when I thought it was necessary.
The Black Python's eggs "feed" on mana for their generation, so I must provide the missing mana for the egg. Fortunately, the egg's mother had already provided the 97% amount the egg needs to hatch.
And Veritus did everything possible to leave this percentage at 99.5% so that I could supply the last part. The moment I do that, a Black Python will be born from the egg.
The delay Veritus had in leaving it at this percentage shows how exaggerated and the amount of mana this egg needs.
So now it's my turn. As soon as the Black Python hatches, it will define the first thing it sees as its mother, so it's in an isolated room in the basement precisely to avoid the risk of failure.
