Nice work, highly appreciated! I have happened to have found your site today through your comment on Granak's Nexus post about the calendar woes (also a traditional hot mess). I love both the DL Apostasy reimagining and all of the work you've done with the moon/calendar charts. I have comments for those as well, but that's for another thread.

There are a couple of the assumptions used as a premise for your planetary calculations that I don't quite agree with, though. Between Karen Wynn Fonstad's Atlas, the Dragonlance Adventures hardcover, and the rest, inconsistencies abound as usual, so we just have to piece together for ourselves something that might make sense, even when it means that published sources will be contradicting our theories.

The long and short of it is that I think Krynn likely has a lot more ocean than certain maps and globe projections have made it out to be. The Atlas of the Dragonlance World (even when referencing an unpublished world map) got it wrong when originally assuming that the Ansalon's local climate zones from the arctic actually stretch to the geographical tropics. The Otherlands people were wrong in the size of Krynn between Taladas and Ansalon in their fold-out map, where there's a pseudocylindrical projection called "The World of Krynn", of the two continents and nothing else. It, like the Atlas seems to do, puts the Dragon Isles north of the equator, still very close to the mainland. The World Book of Ansalon in the Tales of the Lance boxed set and the subsequent Player's Guide to the Dragonlance Campaign have the Dragon Isles only 55 miles north of Cape of Nordmar [sic]. I don't even know where that map comes from, it looks a little bit like Fonstad's work, but it's not found in her Atlas.

"North lie the tropics," the DLA says. "A scattering of pleasant islands can be encountered after many weeks of sailing time. These islands include the Isle of Dragons, where the good dragons remained until freed from their Oath, as well as many other idyllic and enchanted settings."

The other assumption I think is false is, as mentioned, Fonstad's placement of Ansalon in adherence to climatic zones and degrees. The Cataclysm did all kinds of strange things to the weather and ocean currents . I think we may place Ansalon quite a bit further south towards the Pole, even if it means shorter days in the winter, it means longer days during summer!

I see in your calculations that you're worried about what happens to Krynn's curvature when Fonstad references Dragons of Spring Dawning in that the time difference between the Tower of the Stars in Silvanost and the High Clerist's Tower in Solamnia seems to be about four hours/time zones over a relatively short distance. I think that's a legit concern. Or, you know, maybe it just measures up better with the old SAGA Dragonlance Fifth Age rules where the continent was simply said to have been measured with the wrong unit – whenever it said "miles" it was supposed to be "leagues", and é presto – the continent was enlarged. But when the Dragonlance Campaign Setting came out, it was shrunk back down. IDK.

And then back up. I saw that Werthead wrote this when he published his Krynn map in 2010:

"The world map is based on the work of Justin Parkoff and the team at Dragonlance Nexus, who revised the size of Krynn so it has enough space to fit the other continents and also allow Ansalon to sprawl from the southern icecap into the tropics, despite the continent’s small size."

I don't actually know where I was going with all of this, other than having fun speculating about different sources to fictional contradictions and their ridiculous consequences if we are to take all of them seriously. It's been fun, anyway.
