Overview
Ancient Burial Ground is not sufficiently documented in the sources I could verify for the base game of Ghost of Yōtei. A search for the exact name alongside the game title produced no reliable, location-specific result. The main accessible community wiki describes Ghost of Yōtei as an open-world game set in Ezo in 1603, with seven broad regions and a large number of named activities and landmarks, but it does not expose an indexed page confirming Ancient Burial Ground as one of them.
Until the name can be matched to an in-game map label, screenshot, guide entry or supplied source, its boundaries and hierarchy cannot be resolved responsibly.
