Trudvang is originally the name of a part of Asgard; Thor is a Trudvanger. Trudvangite.

In this context it's a world setting for the Swedish role-playing game Drakar och Demoner (”Dragons and Demons”; not the same game as Dungeons & Dragons). One of Trudvang's visual hallmarks is its fairy tale inspired trolls with their… prominent noses.

I scrapped the idea because I had finally learned not to base my strips on internal humor for Swedish tabletop gamers.

Another local reference – the sneezing powder salesman has a tish with the text ”Butt Erik”. Sweden's most well-known store of party novelties is called Butterick's.
