Vertz

Marcus and Ida Vertz are a named NPC couple who appear in the game, but have no obvious purpose or relation to the plot. They first appear in Chapter II where they live opposite the hospital, just a bit east of Angus' house near the corner leading to Market Street, but then, in Chapter III, they mysteriously move to a house in the slums.

Their movements are never explained. They are never mentioned by any other characters in the game, so they make for some interesting speculation, but have no bearing on the plot of the game.
