Location: Road of Sacrifices
The Crystal Sages once served as spiritual guides to the scholars of the Grand Archives and one went on to ally with the Undead Legion of Farron. So, at some point, there was break in relations between the scholars of the Grand Archives and the heretic sorcerers allied with Farron. The scholars were nevertheless followers of the Crystal Sage, though, and can thus trace their lineage back to Big Hat Logan, the famous sorcerer who studied the dangerous insights of Seath the Scaleless. Logan's fateful meeting with Seath led to a branch of sorcery that has been carried on by the Crystal Sages. So, the scholars also carried on the work of Seath. The cursed hands that emerge from the books in the archives are reminiscent of Big Hat Logan turning hollow by reading from the books in Seath's archives.
