As they walked towards the merchant's district, Daimon observed the city, spying on the realms of some of the bystanders that happened to be walking all over the place.
A city that has such a complex prison that connects with the border of another sea can't be a non-important place, so it would be not bad to assume they were in an important spot of the Mermen Sea.
'The concentration of Arch ranks is pretty much similar to a major city at Lykos, so leaving aside the Emperor ranks, they are in the same level as us', thought Daimon.
It didn't take them long to reach the merchant's district, it was easy to notice because the streets that conformed it, were pretty much crowded, with lines forming at some locals, and some street stalls too.
