That's a reasonable approach, if the orb is unclaimed, as it was in Viveca's world.

But if someone has it... We can ask them to hand it over, but often, those who have it have some goal they're desperate to achieve, and won't hand it over until they've accomplished it. 'Staying out of it' and 'Recovering the orb as soon as possible' would be contradictory goals.

And the one time we tried to steal an orb in a bargain... it was a disaster.
