Addition of Nothingness!
On the 9th day since Lilith used her Insight Scroll, Erix, and Rin finally made a second big breakthrough since the last one seven days ago.
They successfully broke through in their Chaos concept, reaching 3rd realm in it!
Most importantly, they finally reached a breaking point in their spirituality shortly afterward and transformed their Spirit source into Aethir source! They didn't complete the 3rd stage of Way of Unfettered, but finally finished the requirement to complete it. Now they just had to work towards awakening Aethir Mystic Intent in the usual daily 30-minute nightmares.
Both of them were under the Dreanox Tree and they had just finished a Limitless Plane session of 1 hour where they reached the 3rd realm in the Chaos concept. They still had to spend 30 minutes of it in the evening for the torture of Way of Unfettered's 3rd stage and the sudden breakthrough of Aethir awakening occurred on both of them at the same time as if they were synchronized.
