Not sure that the Dragonlance Nordmen are basically fantasy Scandinavians. They have the physical looks and the name meaning people of the north but that seems to be it. Ansalon is in the southern hemisphere. Nordmaar is the northernmost point on the continent, it includes the most tropical part of the continent, steamy jungles where the civilized Nordmen live under the single rule of the Nordmaar king, and more arid areas subject to their "close cousins" the nomadic horse barbarians who serve the Khan of the Southern Wastes.
The names of the Nordmen tribes in the wiki are not particularly Norse:
The nearby Minotaurs of the Blood Sea are the ones I remember being known for naval piracy and raiding in the setting. Nordmaar is not known for its trade either.
For Krynn (but also for some of the other worlds) there’s always a caveat that motifs are especially blended. I’m not actually saying the Nordmen are outright Norsemen. They’re Norsemen in a jungle clime with Aztec names. Whose coastal folk are Black. And whose Horse Barbarian cousins are Turko-Mongolic khans. And whose culture is sifted through the Krynnish aesthetic and mythology (no Odin and Aesir!).
A cultural entry means different things depending on which world it’s from. For Mystara, it often means a close parallel. For Oerth, a more blended parallel. For Krynn, even more blended, to the extent that it’s only one of several “source motifs” for that culture, covering only a single aspect.
When I post the Norse-Germanic section, you’ll see that spectrum too:
-Mystara’s Northern Reaches. Very close parallel to earthly Norse.
-Oerth’s Snow & Ice Barbarians are more fantastic.
-As are Toril’s Uthgardt Barbarians.
-And even moreso, Krynn’s Nordmen.
-If there are any Norse/Viking motifs in Eberron, I imagine they are even more effervescent.
The listing of Krynnish Nordmen under ~Norse-Germanic doesn’t mean they are as parallel as the other worlds’ Norsemen analogues.
Same applies to all the sections on the chart.
