Telecanter, over at Telecanter's Recedng Rules, did a series of posts on adding wonders to your sandbox. So what defines a wonder? Something different, unique, or fantastic that would be mythical in our own experience in this world. I am a fan of the grim and gritty fantasy experience, but I still think there is room, no a real need, for the strange and fantastic to perplex players and add a sense of fantasy to the game.
So I put together a booklet of all of Telecanter's 100 Wonders Worth Exploring. If you print the PDF in booklet form it will fit nicely with the rest of your Heroes & Other Worlds game books! So if you are building a sandbox and want to add a little something wondrous for your players to discover, Telecanter's work is an excellent resource! You can find it in the Heroes & Other Worlds downloads and can download it here!
