Around 400 years ago, Beatrice was created by Echidna. She helped her with her experiments, such as the Sanctuary Barrier, though she wasn't told everything as she didn't know that Ryuzu Meyer would be sealed in a crystal. Sometime later, Echidna ordered her to stand guard over the library while she waited for "that person," an order which she diligently followed.

Spoiler

After numerous and painful attempts to convince her to leave the library Subaru succeeded, and Beatrice became his contract spirit.
