Invention
The gunpowder requested by Harsha was brought to the mansion swiftly by the regional leader, Santosh. He had brought the gunpowder from a European merchant in bulk. He had bought them with the intent of helping out.
Santosh had previously seen the destruction caused by the ship cannons in Goa. So he always believed gunpowder would be a powerful weapon if he learned to harness it.
Although the Empire had cannons and gunpowder, their use and maintenance were handled by the Royal Family and Emperor personally. The cannons in the Empire's arsenal were very old compared to the ones that Europeans have been utilizing for their endeavors.
Lack of innovation in weapons was not helping the Empire as others began investing in the technology. If the empire falls behind in the arms race, it would prove to be fatal for the future.
Viswa was following the prince as he was inspecting the gunpowder and looking around to make something.
