I have a argument with my friends.
It's about a NPC which named Agmaer, in Dawnguard of the game Skyrim.
When the first time the new guy Agmaer talk to Isran(the Dawnguard leader), he said that he use his father's axe.
Is this Easter egg from the movie《Abraham Lincoln: Vampire Hunter》?

I haven't seen the movie, but given that Nords like to use axes as weapons and place sacred value upon family heirlooms, I doubt it.
