Mago isn’t your character dude, certainly too important to just use like a regular NPC. Mago is pretty much the big bad of the RP, and thus the GM’s character.

There is a way this could work and that’s simply changing Mago to someone else, like an important lord or advisor to Mago. I’m sure the usurper King has allies within his court to have taken over the kingdom with such relative ease. 

Though I should also mention that unless your character’s action is taking place ahead of time in the current IC, the orc’s Attack didn’t happen “yesterday evening”, but literally an hour ago. I got no idea how far the besieged city is to the capital, but I imagine it’s further than an hour flight by messager crow.
