I'm writing and DMing a campaign based around members of a nonprofit organization in a province of a decaying empire undergoing a civil war.
The player characters are new members of the NGO, who are being given an orientation by their Program Coordinator (basically their boss) when the city they're in comes under attack by the government's troops. The entire NGO's presence in the region is destroyed and the PCs and the program coordinator have to decide what to do next.
The program coordinator is the "Gandalf"-like figure in that she potentially directs the quest and accompanies the PCs on their adventure to find and return 12 children still missing after the raid. This may or may not spiral out of control into joining the insurrection to topple the evil emperor depending on the choices of the players in the campaign.
One member of my prospective group actually works at a nonprofit organization and it just occurred to me that her perspective might bring something interesting to the table that I couldn't. I was thinking of asking that member if she might be interested in taking on the role, with the sole precondition being that finding those children is the character's main motivation, and everything else around that is up to her.
Point of clarification: I've previously discussed the campaign with said player and she expressed an interest in the idea she'd be part of a team making the kinds of decisions NGOs regularly have to make when they're working in a conflict zone, but in the context of a fantasy world. So it's not an ask out of nowhere.
Three linked questions:
Is it feasible or advisable for me to delegate so much storytelling authority to a single player?
Is it feasible or advisable for me to do so given that this player is new to tabletop gaming?
If the answers to both #1 and #2 are "yes", what are some things I should consider when helping to come up with the character?
