Eternal Winter City was the non-freezing port in the northern part given to Great Tang Group by the Dwarves as payment to settle debts.
This port is a natural ice-free harbor, arguably the best in the entire Dwarf Ice Cold Kingdom.
Though they were somewhat reluctant to part with it, the fact was that by the standards of Great Tang Group, this might be the only non-freezing port in the Ice Cold Kingdom territory that could be used immediately.
Before the workers of Great Tang Group arrived, this place seemed to have a smaller scale than even the Osa Military Harbor which the Elves had ceded to Great Tang Group.
Or rather, comparing it to the Osa Port which was already undergoing thorough reconstruction by Great Tang Group was perhaps claiming too much credit.
The annual throughput here was very limited, which was an important criterion for Great Tang Group to determine the usefulness of a port.
