Hildibrand for relic? Really?

[Vahlnir]

I'm incredibly curious why it will unlock with the Somewhat Further line myself. But I trust that they have a solid reason. There's something in the questline up to that point that is going to be important or at least will establish something that needs to be established. We may not even fully understand the connection until we're at the end of the questline.

My theory is that it is related to Gilgamesh somehow. He's a master of weapons, after all.
