I’ll go a step further: Dvalin isn’t a person. Dvalin is a god.
We might expect people to act like people. But gods are not people, and it’s a mistake to assume that a god should act like a person.
Dvalin is an infinite object that transcends time and space that represents the concept and ideal of dwarven law.
Dvalin isn’t a thing that can just stop being Dvalin because it’s not convenient to be Dvalin for a while.
Dvalin is... Dvalin.
