Just have to make some final adjustments to Quennan Amakiir, Drow Druid and visitor to Silverymoon The DM might illuminate me here: The Far Traveller background specifically mentions the Underdark. But our starting locations seems a place like no other. Would much of the flavor of that background be wasted in Silverymoon?
Hi KCC! We can make the Far Traveller feature work but it probably won't be as pronounced as usual once we get into the Fey Wild. They're used to some
pretty strange folks there. I think it
would be fairly unique in Silverymoon, but we won't be in Silverymoon itself - the adventure will start outside the city at the Witchlight Carnival. The Silverymoon location is mostly for backstory and situating our imaginations for Forgotten Realms fans :)
I'd say if you want your background feature to definitely matter, Far Traveller is a bit of a gamble.
