Special Experiment

Astralophone surface is illuminated, and you hear the voice of the Overmind:

"You'll receive a special artifact. Its purpose... However, you'd better not know the details on this experiment. Just remember that it is vital for us.

We don't need much from you. Go on with the extermination of demons on the Twilight Isle. Not all of them, but particular species called Demon Weepers. You can found them on the astral coast to the east from the chains. Make sure to activate the device in combat, or before it starts. We have no use for data collected from corpse. Destroy 10 demons while carrying this device. As soon as you complete the task, come back to the Astralophone for further instructions."

When you touch the cold surface of Astralophone, you can hear a hissing voice of a Wormface:

"So, the first phase of the experiment is complete. The results are not yet clear, but we don't have enough time for detailed analysis. It's time to start the second phase."
