Lizzie and Josie Saltzman celebrate their sweet sixteen. Having been born in 2014, that places the timeline in the year 2030. This however is a continuity error. There was a previous time jump of seven years in May 2019, leading up to 2026, followed by another two year time jump from The Originals' finale and Legacies premiere.
Lizzie sits in her room reading from a grimoire. The grimoire, however, is in fact one of Esther's. It's never explained how she obtained it, though the likely answer is that Hope took it with her when she left New Orleans. This, however, is never elaborated upon.
Davina goes through Esther's grimoire to find a spell.
Freya's Grimoire contains a copy of two pages from Esther's grimoire
