This magical key is one of several made by a
secret order of historians and archivists. While
holding the key, you can use an action to twist
the key, as if you were unlocking a door. When
you do, a magical, spectral door slowly appears
in front of you over the course of 1 minute,
duplicating the effect of the magnificent mansion
spell with the following change. The dwelling
always includes a large library that magically
includes copies of books, scrolls, maps, and
more. The library does not count toward the
total amount of space created by the spell. Its
contents are strangely organized and seemingly
change each time the key is used. A creature can
visit the library and attempt to uncover a piece
of knowledge, such as ancient poetry, the history
of a forgotten kingdom, or the family lineage of a
tyrannical king. The GM determines the checks
and DCs needed to locate a given piece of infor-
mation. For example, a book of foreign nursery
rhymes may be easy to find, but a copy of necro-
mantic research documents would be extremely
difficult, if not impossible.
When the spell ends, the key can't be used this
way again for 24 hours.
