Brave Arkham Detectives Battle the Elder Evil Step back to early 20th Century New England. Here, the horrible "Great Old Ones"-mysterious inhabitants of a dark, unfathomable void-seek entry into our world. One of their imprisoned overlords gathers them, just as his worldly servants open portals throughout Arkham for the coming onslaught. Only Salem's master witch, Robert Craven, holds the key to safeguarding mankind.
