It's one of Niddhoggr's heads. It sort of acts as a messenger and corrupter for the Others. Giving mortals a taste of what the Others can offer without the negative side affects, but no more so their left wanting and will heedlessly seek out the Other's "gifts". It's pretty much completely on the Other's side as the current state of things are since Nidhoggr lives to do wrong and helping the Others accomplishes that goal rather nicely.
