Now I am thinking about the Krynnian aasimars could be the offspring of the irdas (the bloodline that wasn't tainted).
WotC has to choose what to do with the continuity after the "war of the souls". My hope is the famous heroes of the lance to be ascended into "legendary heroes", practically quasigods. (and could Raitslin to become a vestige patron?).
Sithicus can be perfect place if you want to survive an undead apocalypse where the monsters are controled by the dark-lord. It can be also a right place for half-vistani (or "vistani-touched", human children who were adopted, not kidnapped, because the seers discovered something about their future). Vampire kenders can be perfect for horror stories with some piece of dark comedy.
* Do you think a rewritting of the original Dragonlance modules could be possible?
* Other idea is the Krynnspace where Raitslin caused the cataclysm suffering an attempt of invasion by the Voldoni empire (a faction from Spelljammer) and here the reaction by the divine necromancer would be the return toward the life of the gnomes with their crazy inventions. And in this timeline his half-irda daughter is real. In the end, he accepts the sacrifice for his daughter, and she achieves a happy ending with many descendants.
Crysania Tarinius could be the main character of her own story of second opportunity. The god Raistlin is sent to the Athaspace where he loses his divine power. Then the mystic Crysania Tarinius is allowed to travel there where she can use psionic powers. She is an "ardent" (like a psionic cleric) and she helps Raistlin to survive and to start a new life. Raitslin rediscovers the lost arts of life-shaping, becoming a "haruspex"(the biopunk cousin of the necromancer). The surprise is also a "piece" of Crysania is reborn as a female irda in the past, becoming the future mother of Raistlin's daguther. OK, it is a crazy idea.
* Dragonlance is not a good settings for sourcebooks too focused into crunch or player options. But it could be fabulous for a family-friendly LEGO adaptation like a CGI animated show or a videogame with that dumb and innocent humor. (you can imagine Tas breaking the 4th wall and like this).
* If there is an update of Dark Sun then we should see a future UA article about Athasian PC species the tari(ratfolk), Athasian genasi(ember, magma, sun and sand), elflings and the mulzhennedars(muls).
