At present, I have a ransom quest to recover a kidnapped pawn.
I can see that I can use a Signal Fire to contact other factions (in the same way that I'd use a Comms Console), but is there any equivalent to a Trade Beacon?

The ransom wants me to have the required amount of silver within range of a trade beacon - but without microelectronics, the usual method isn't available.
What should I be doing to get this ransom paid to the other faction? :-)
