"Bloody hell! The things one has to do to make progress round here! While I sort things out, you kill our monarch, destroy our spellcasting abilities, kill random people, incite open rebellion and try to sell poison! Well, I don't know how the King became convinced you were worth listening to, but I've had enough!"
Sir Biscuits marches into the palace, yelling at the other advisors furiously, an oddly long and very dark red cloak flowing behind him.
"You know what? I tried to come to this place, settle down, it seemed nice, I had to save it from a few crises, but that wasn't too bad. I was in a... bad place, and this helped me get out of a rut. But no, I try to be cheerful, and everyone wrecks everything. Well you know what? It was Dark Lord Ponzi's little finger in my rucksack! And if I have to introduce slavery to save you lot from yourselves? Well so be it! I actuall enjoy being evil, you know, why bother hiding it! And to start with, I'm going to use that bloody dark magic everyone's was oh-so-worried about when I arrived, to save this bloody place! You were too stupid to even notice my necromancerial leanings, and the one we've got is totally useless anyhow, so I might as well replace him. Hah! "Sire Biscuits McGee"? Talk about an obvious anagram! "Cities Beg, Scum Rise" is more like it!"
"Well, some idiot should probably try to sure the king from alcohol induced spontaneous liver combustion - and I did pick up a few tea leaves from my travels in the Northlands, so you might want to try those. Now, I need a volunteer to lead the army into the inevitable glorious final charges against the rebels - a necromancer needs some bodies to reanimate, after all."
Swirling my Cloak of Dark Red Darkness about me, assume my true form as the famed necromancer Hobnob McEvil (translation - Cities Beg, Scum Rise). Leave those magical goblin tealeaves, if I kept them from the start, with instructions, in case anyone wants to mix them into a drink for the king. Then cast a grievous spell of dark financial magic at opposing nobles to destroy their gold reserves and bases.
