This module has so many great ideas. You sparked my interest with the Owlbear theme but your original setting of Murraya kept me hooked. A Thailand inspired fantasy setting is such a wonderful idea!
So much great stuff happening on just page 4 alone providing for a great background. And I agree that the additional firearms and trap mechanics are a great supplement. And last but not least: love the handdrawn art style as well :)
Really great job with this mini-hexcrawl You suprised me a lot!
