So... I made an Ingvanr reference in my game and accidentally made it critical to the lore. Vikings were always in the story, Ingvanr as one of them was not. Hope you like it:
The only good one out of the viking ancestors, he just wanted to find the sun to cure his awful brothers of a terrible disease. In the end, he was not rewarded for his courageous acts but we shall see, perhaps he will return in some manner... Glad you liked it!
