You can generally assume that your character can trivially obtain any equipment such as weapons they may use, but what about more substantial things? Whilst a barter system is used across the Myriad Nations, and there are still some who deal in the currency of the Ennarian colonists (the Riel), these don't tend to be sufficient to do more complex things, or things that tend to be useful to adventurers. For that, what becomes important is the network of favours and goodwill owed by organisations you've worked with before.
