It’s quite easy to draw a line from Demon’s Souls all the way to Elden Ring. You can argue that all of developer FromSoftware’s games since that seminal title have been expansions on the same idea, even if the individual details and specifics can vary drastically.
This doesn’t just refer to the general feel, game mechanics or structure; FromSoft has also been known to reiterate on old ideas with every new game, and Elden Ring is no exception.
One of the more unique enemy designs in Elden Ring is the Night’s Cavalry. These units appear only at night, and roam certain areas hunting for you, the Tarnished. It is believed that they are the hands of the Fell Omen (Margit/Morgott).
