Olin Gisir

"Hush! Know that we walk in the ruins of the temple of Astaroth, a demon lord of the Abyss. It is said that the demon sleeps here still, seeking to poison the words of those who wander in. Luckily, I know just the spells to ensure that he remains asleep ..."

- Meraera of the Olin Gisiae

Olin Gisir means "secret keeper" in Elven, which is precisely what these scholar-mages were. Elven lifespans were many times those of humans, and this brought along with it secrets that were best left secret.

Background
Olin Gisiae were elite elven or half-elven lorekeepers who took it upon themselves to protect dark secrets and ancient magics from those who would have exploited them, making them much like the Cult of the Shattered Peak in that respect.
