Gravenhollow

Gravenhollow was mystic library in Underdark.

The library was a peculiar building for many reason: it was outside the normal time of Toril, everybody inside it understand all language, was bigger in inside, stopped the works of magic, except divination and nobody can find it without it's keepers will. A very peculiar trait of Gravenhollow was that it "remembers" all who have walked its halls, as well as those who will visit the library in the future. Exploring the library, apparitions constantly flicked in and out of existence around them the echoes of those who have come or will come to Ghavenhollow in search of knowledge.
