What is The Eye doing?

[Nalien]

Probably Hresvelgr. Or perhaps Haldrath.

I'd go with Haldrath, given he was kept in an sort of undying state while directly connected to the eye twin... Plus, you know, he'd have plenty of reason to lament the rift between man and dragon, given he helped create it... Last we ever saw of him (via Echo) he was set to bear the sins of his father until death, so he was certainly under no illusions that what they did was somehow just...
