Valhalla wanted to show the couple around, but they did not want to occupy anymore of his time so they explored on their own.
(And dude, they didn't want that kind of attention. The City Lord escorting them around? No thanks.)
The couple were granted unlimited access anywhere in the City, except for the top secret and highest security areas, such as certain parts of the Royal Library and the sensitive areas of the barracks.
Regardless, this was actually already a higher access than most relatives had.
Not that the brothers had a lot of relatives.
Due to the low fertility rate of powerhouses, added with low fertility of orcblood, their family tree had always been very, very thin.
Even the ancestors with massive harems would probably just have one or two children at best. The worst example was Valhalla's granduncle, who had a hundred beauties in his harem yet none of them gave birth.
