The Fiends had tried to attack and expand several times in the last 2 centuries since the massive assassination attempts.
The forces deployed were far more successful in containing them but the limits became clear quickly to both sides.
Shard Tiers were being lost faster than they could be replaced but the sheer number kept the issue at bay for the present.
Fiends had time, however, and seemed more interested in solidifying their power base to have an army of Immortal Fiends unlike anything they had before the Cataclysm.
The old records made it clear that not all Fiend powers had been allies so the issue had not been so cut and dried. Each local area had to deal with their own problems.
The very limited space reclaimed by the cultivators did not even make a drop in the bucket even after nearly 8000 years since the Celestial Fields was restored.
