What does The First Shadow establish that the series never did?Fiction

In-universe lore. Claims are judged against the fiction's own canon, not the real world.

Stranger Things: The First Shadow is a stage play, and it is canon. Written by Kate Trefry from an original story by the Duffer Brothers, Jack Thorne and Trefry, the 1959-set prequel fills in Henry Creel's origin, Dr Brenner's inheritance from the USS Eldridge, and a whole character the episodes never had.
