Purple = Necromancy, Red = Combat

There is some tell of strange happenings over in the graveyard. Well, quite a bit of tell, given that YOU know about it. Reports are conflicting and confused, but piecing together dozens of half formed stories obtained from 'borrowed' (and terrified) peasants has brought you this realization: The beasts are congregating. Rats, cats, bats*, all are forming ranks to create gigantic swarms of tiny evils. Some of the more observant among the ... 'help' said that there appeared to some sort of magical gem in the center of the encroaching flurry of fur. A magical gem... almost like those gems that you misplaced some years ago. Well, they were bound to turn up eventually.

Your course of action is clear. You must re-obtain these gems from the native population, with as many casualties as necessary. Although... rodents, felines, and avians are all such distasteful creatures. Hm. No point in getting yourself dirty. You still have that last gem, right?

Your course of action is somewhat more clear than before. You must use your great necromantic powers to imbue a gem with the power to create a swarm of your own. You'll start small, but then again, you DO have necromantic powers. Growth shouldn't be an issue.

One final note: Undead vermin are not too powerful on their own. You'll have to imbue them with combative spirit to get any sort of reasonable result in disposing of the natives. Be careful though, they aren't meant to handle that sort of power and will suffer under the strain. They'll all move slowly and the weaker among them will start to burn up. Be sparing in your powers.

One even more final note: You may have once again been a bit too judicious in your usage of power, and it appears your gem will explode in around two minutes. Be quick.
