An ordinary saddlebag that looks to be stuffed with books and scrolls.
You can place as many books as you want inside and withdraw them as you please.
Additionally, you can attempt to summon a book or scroll containing the information you wish to know on a DC20 Intelligence check (unless the DM says its lost or hidden knowledge).
Placing a bag of Sage inside an extradimensional space created by a handy haversack, portable hole, or similar item instantly destroys both items and opens a gate to the Astral Plane. The gate originates where the one item was placed inside the other. Any creature within 10 feet of the gate is sucked through it to a random location on the Astral Plane. The gate then closes. The gate is one-way only and can't be reopened.
Notes: Utility, Container
