The Hidden Library (5E)

From publisher blurb:

This adventure is for 4-6 heroes of 3rd level, for a one-shot adventure for Fifth Edition (5e). (Though this may take 1-2 sessions to complete).

Within the shadows of the ancient, ivy-encased library, rumored to house the world's lost knowledge, lies a secret passage to realms untold. And they only have one night to do so.

Here, players will navigate through enchanted archives and outwit the guardians. While the library's true secret might not be what legends foretold, the heroes could emerge as saviors of knowledge, earning the eternal gratitude of some of the realm's greatest minds.

This product includes 2 PDFs: The adventure itself (14 pages) and an easy-reference bestiary (25 pages).
