Memory Palace
ITEM 14A memory palace is an elaborate magical structure that safely stores memories for easy access. It appears to be a miniature Taldan villa small enough to fit in the palm of a human hand.
Memories you have imprinted on a node can be mentally accessed at any time by a creature holding the memory palace in its miniature form, regardless of who imprinted them. This grants a +2 item bonus to Recall Knowledge checks relating to details specifically occurring within the memory. What exactly qualifies is up to the GM's discretion, but a node shouldn't grant the benefits for most uses of a given skill. For example, a node dedicated to a book about trees found in the Mwangi Expanse would help with Recall Knowledge checks for such trees, but it wouldn't grant the benefits for all Nature checks to Recall Knowledge.
A memory palace node can also store the text from a spellbook or magical tome, but these memories aren't a substitute for having the book in your possession. A wizard can't prepare spells from a memory palace, though they could use it as source material to try to Learn a Spell. However, since storing spells in a node would only benefit someone else who later discovers the memory palace, few choose to take such an action. The memories contained within the nodes aren't real, and thus don't cause harmful effects, even if the source of the memory was a mental danger. Many memory palaces have leftover memories from previous users-now long dead-imprinted on their various nodes.
