The Shackled City
“Sage” as the psicrystal insists upon being referred to, demanded of Greyjek to allow it to introduce itself to the party during his initial meeting with them on 21 Flocktime, 592 CY. The psicrystal offered its vast stores of knowledge for their use, as it made clear it believed they would fail utterly without them.
Sage behaves as though it is Greyjek’s mentor and that it is permeated by several libraries’ worth of obscure lore from various subjects. Its belief in its capacity for knowledge is unshakable, even though the knowledge it contains is sometimes dubious.
