In the headquarters of Black Sceptre, the battle between Martin and Niril was discussed. The information about the battle was collected by the spies of Black Sceptre.
In the short time, the information collected was directly classified as a secret to almost all members of Black Sceptre other than the leader of Black Sceptre and other leader-level members.
The reason why this information was important for the organization was self-apparent,
The battle between two-atmosphere level beings contained too much experience and many things that most of the other beings use to elevate their power by taking pointers from it.
From the individual perspective, the reason was having to know the experience of two-atmosphere levels and learn from their battle.
From another perspective, the fact that they are living with the Atmosphere Level beings will create too much problem for the Black Sceptre and every other organization.
