Gunpowder

The Empire's Capital was brimming with activity as the carriages entered the Royal Palace. Viswa inspected the materials with a cloth covering his nose from the smell of sulfur. It was the materials that Harsha had ordered for an experiment. 

Viswa found the materials almost instantly; it was easier to find than he thought. The pungent smell of sulfur in the river valleys was strong enough for them to notice. 

'Is this all the materials required?' He double-checked the carriage. Once everything was in place. 

"Go to the training grounds." Viswa ordered. "You may leave the materials there and leave." 

"Yes, Lord." They said and went towards the training grounds. 

Viswa quickly set out to inform Harsha about this. It's been a few days after the meeting with Arnav. 

Entering the study room of the Emperor, Viswa greeted him, taking off the cloth over his nose. The pungent smell was still lingering.
