Pilgrim's Traverse weapons dont glow?

[Cidel]

The two versions of the PT weapons have light shining through the stained glass, which is subtle but lights up in the dark. They're both beautiful in my opinion, though I like the first version better.

So there is a 2nd version of the PT weapons? Does that automatically occur at 100 Aetherpool? I've been asking around in-game and nobody seemed to be sure.
