Ok guys, I need your help: I'm Sir Schemealot, and I'm looking forward to becoming King Schemealot with our foolproof plan!
First thing, the setting:
We're in middle ages like times, and my people lived free in inhospitable, cold lands for ages, happy to be left on our own, grouping in tribes, fighting each other and praying to our divinities. But we were invaded by a medieval superpower coming from far to the south.
They defeated us, but didn't want to live here, so they named a king to rule over us. We had to renounce our religion and bow to this king, but to be honest, things are OK~ish: there is no strict control over our religion, the tribes are united to work more efficiently than ever and our king is, in the end, one of us rather than one of the invaders. (They didn't stick around because of the climate)
Previously a tribe chief, I'm now something akin to a noble, one of the king's advisors; but that's far from enough for someone like me! Moreover, we have to pay a tribute to the sovereign nation, and I consider it to be striping us of our dignity! But I know a few things that could help me take over the power: if we take too long to send the tribute, the sovereign nation will attack, choosing a new king in the process...
If I manage to intercept the tribute and make it look like the king is rebelling, I could denounce him, putting me in prime position to be the new king! With my position, I could forge documents and messages signed by the king, I could stop carrier pigeons and organise bandit attack on the tribute... I'm almost sure some other advisors are also displeased, but I'd rather not chance it if I can.
The sovereign nation is more than 2 weeks away for a messenger on horse, I have more than enough founds and I have a few dozen men that are absolutely loyal to me.
What would be the best plan of action? I don't want to overdo it and kill every messenger/pigeon going south while intercepting the tribute, that would be quite difficult and certainly leave hints of my schemes, no?
So, any idea? Is this achievable? How should I proceed?
P.S.: English isn't my first language, so sorry for any grave mistake... Also, it's my first post, I take all advice!
