>>21013292As for how /∞/ would make it to /rbc/. During the summer seasons, ships would travel through northern part of the holocontinent because a strait was included there as well. /∞/ also has early steamships that could be used as low power ice breakers to break through thinner ice. (Nothing thick, and it would be a slow process because scouts would need to check the thicken of the ice.) when the passage starts to ice over, but not during the winter when it would be totally frozen solid.
Otherwise, ships would come in from the west of /rbc/. first traveling through the indie vtuber continent the traveling up the western coastline of the holocontient and through the newly created strait to /rbc/.
If /rbc/ doesn't have any of their own ships for trading, they could use /∞/ ships for their business as well.
