the shadows and gloom in a way that makes it impossible to forget that, where there is light and life, there is also darkness and decay. [...] Home to numerous species, the most prominent entities who dwell in the Shadowfell are mysterious undead beings called shadows. Shadow dragons and shadow mastiffs can also be found there, along with a host of dark, terrifying creatures like wraiths, spectres, darkweavers and shadow demons. There are also a number of humanoid natives, including gnomes, humans, halflings and beings known as Shadar-Kai".
