The family was located on the main planet of the Sculptor's galaxy, the planet of the Great Volcano.
This planet was named after the volcano that Hephaestus always used for his forge. The heat there was the basis of his forge built in the volcano.
There the family and the rest of the group were well received. They also found a native heir there, who joined the trip and helped them a lot to understand the culture of the place.
Luckily the family was able to get in contact with this native quickly, so they could better understand the culture of the place and not be ripped off....
Because the natives here could really take advantage of his good speech and wisdom. Especially to sell their products. Everyone made it seem as if their products were the most precious thing on the market.
They also knew how to recognize foreigners easily. They were kind and friendly to foreigners but clearly wanted to take advantage of their unfamiliarity.
