Denleaf Stronghold

Paying 10 grams of Solar stone, they received an identification certificate and were granted access to the stronghold.

Once inside, it felt like a different world.

High-tech mechanical devices, makeshift buildings, a street hawking various products, and finally, a thriving plantation.

Shortly after, Liam rented a space to park their mechanical carriage, costing a few grams of solar stone.

On their way here, Liam noticed that the official currency of the stronghold appeared to be solar stone.

It might seem inefficient and troublesome to use stone in grams.

But solar stones are as light as a feather, making a gram of it about the size of a thumb.

Furthermore, there were carving and weighing stations everywhere for processing solar stones.

Liam also understood that, in such a time, a currency wouldn't work unless it held significant value.

Like food and water, which could be used for bartering.
