Gloomy Depths - Link Contamination

Judging by previous requests, Edred's involvement in selling illegal legacies is almost confirmed.
His subsequent meeting with Reference Mirror made it clear that the actions of the Cabbage Mission have caused significant trouble for Reference Mirror, even resulting in the Creed closely monitoring the guild. Reference Mirror referred to this situation as link contamination, which may imply they've been using this channel to sell illicit Legacies for a long time.

But what sort of Bapharian Legacy could be worthy of such commotion? What kind of magic do those lost goods possess that they have unbalanced the long-term peace, and even forced the Creed to intervene in the Gloomy Depths?

Furthermore, both parties' identities are quite intriguing.
During their meeting, Reference Mirror addressed Edred as "Mr. Edred of the Desert". Along with his ever-mysterious motives, this title suggests he is involved with more than one faction. Even Sabine mentioned that Edred has provoked entities whose names are never spoken.

These fragments of information gradually outlined a network that had long existed, but never been truly detected. Sabine's efforts might just have left a permanent mark somewhere in this invisible mass.
