And then WotC followed that example ( ttrpg.network )

Despite Margareth Weiss and Tracy Hickman's statement that Krynn has no Lycathropes, Orcs or Drow, TSR would publish a werewolf adventure placed near Daggard Keep in First Edition supplement World of Krynn. I lowkey suspect the Krynnish part of Vecna: Eve of Ruin was a reference to that.
