Got it after your recent clue @Gauri03. Spoiler I struggled a lot to connect Periyar and Capsicum and what clever clues they are!
When I think I got it there is a bottle of bubbly that doesn’t fit in my course. And an old stamp also
Spoiler: For Laks Bubbly is two minor keywords. If you can read the bottle, both are right on it. The stamp is more than a stamp. There is a name that points to an even more famous moniker. That and the capsicum are pretty big clues. Put them together with the ship clue and you have your answer!
Thank you for creating a spoiler around my statement @Gauri03. I thought those words were just referring to two of your image clues and said it in open. But I see your reason now.
Spoiler port city under the Chera rulers where the Romans had built a temple of Augustus Gauri this was an easy one if my guess is correct. was able to connect all image clues together.
Spoiler I can’t connect the spice route to the bubbly(name isn’t ringing a bell). Sort of guessed the port thanks to the Vatican and Oia but I still think something is off. I’ll wait for your explanation.
