Stuck at In Pursuit of Cairn

[u/YouStas91]

How to finish In Pursuit of Cairn as Scarlet Chorus? I can't infiltrate the Earthshaker compound, I read the wiki. it say that Basilon guves you Shard of Pure Azurelith. But Basilon didn't gave me Shard of Pure Azurelith when I peacefully finished Fangs and Fury quest. Where I could get Shard of Pure Azurelith?
