The darkest light

I have no idea what this oil lamp was referred to as by Torak, I just call it the darkest light, as it was called in Saeunn's prophecy. It is a part of the three, or four, objects referred to confusingly as the Nanuak, though they just had a whole lot of Nanuak in them, that is, some of the strongest bits of it. It was more of a sandstone bowl, with a little oil left in it. Some unfortunate random dude had frozen to death on a glacier, and Torak stole his lamp... and brought it to beg to the World Spirit on its mountain.
