A little problem with Cultists

The Black Hand Cult

Kalorus usually doesn't have a problem taking down a bunch of weak mortals who think they can summon demons. Most can't, and the ones that do end up getting killed by their own creation. But I did some research on Moscow, and a Cult, by the name of the Black Hand (Pretty cliche right?) plans to summon a demon in the Kremlin. This wouldn't be a problem, seeing as the security at the Kremlin is pretty tight over all, and it takes a pretty stealthy approach to pass by, but they managed to steal a magical item from a ruin in Saudi Arabia. It is a miniature staff, with an orb at the end. A demonic orb.

As some may know, I have a dark history with demon orbs (Most involve almost dying due to its mystical potency). It may also be known that with such a powerful artifact, it is near impossible to fail at a summon. Once the Cult creates a summoning circle, nothing can stop the beast that appears within it. So, in short. You must...

1- Take down The Black Hand Cult
2- Protect the Kremlin
3- Extract the demon orb
4 (If it gets to this)- Kill the demon that they summon, although I hope that this is not the case.

Note: If we are efficient enough, we should be able to extract the demon orb quickly and efficiently. The Cult shouldn't know how to wield the staff, so they cannot use it as a powerful weapon, only a summoning device.
