Damien paid the Left Minister a visit in the middle of the night. He received an urgent message that something had happened to the pharmacy business of the Left Minister in Prazia, and his presence was badly needed. The Left Minister gritted his teeth when he heard it. Something must've happened to his private army, and not to his pharmacy business.
After disposing of Doctors Franco and Hugo, the Left Minister found someone who helped him develop a kind of drug that could enhance the stamina and strength of a soldier. The first few trials were unsuccessful. They lost at least twenty men before the drug was perfected. For the Left Minister, it was all worth it. He could easily replace the casualties of the experiments with better ones. He had the new drug to thank for.
The message was sent by Duke Mion, who was Doctor Hugo's eldest son. The Lef Minister knew then that something must've happened to the drug or the soldiers that needed his presence badly.
