( Dronacharya's Pov , On the day of the heist )
Dronacharya infected the Dog master , the tunneler that he knew from his past life knowledge with a life threatening poison whose antidote was only available with dronacharya.
It was a 100% d*** move by him to threaten an NPC with his life to make him comply into doing his schemes as this was a new low for even someone as shameless as dronacharya.
Nonetheless his shamelessness paid off as the Dog master had to accede to his wishes and comply . Using his sniffing dogs to open a hidden tunnel that he had found during his days as a drugs smuggler in the holy city , which apparently went right upto the heart of the church's vault.
