I’m currently running Lost Mine of Phandelver so no idea what ‘time period’ I’m playing in. The only reference I’ve used to the past so far in the fall of Phandalin by Orcs. They haven’t seen a world map yet either. Lost Mine is officially a bit nebulous in date for DM convenience, though there are detailed internal WotC timelines so as to keep things straight (i.e. novels). Safe to say: 1490s DR.
