Who says? Sparx outright admits that Cynder is sexy. There you go: one species in LoS is attracted to another one. In fact, Sparx shows just as much interest, if not more, in Cynder than Spyro does. What it boils down to is this: LoS is a fantasy, and in a fantasy, anybody can pair up with anyone they like, regardless of species. It's cool to like dragon/dragon pairings, but they don't exclude dragon/other creature pairings. I know it's a bit overwrought, but saying one character can't love another just because they're different species always sounds a bit too much like "but you're white, and he's...ew, black...you can't get married!" to me and it makes me rather uncomfortable. And it does stunt the imagination unfairly. We all know how two dragons pair up and interact, so where's the fun in that? But a dragonfly and a dragon, or a dragon and a faun? Now those are some pairings I like to see explored!
Sparx saying that stuff was one of the out-of-place things in my opinion in the series, and I don't really consider him to really be attracted by Cynder, especially since she tried to eat him (yeah, she's a maneater, heh heh). As for LoS, I at least personally found it to be more concerned with being realistic than what can be said of the much more carefree attitude of the earlier Spyro games, where dragons were bipedal, different species fell in love with each other, etc. That's the reason behind it originally feeling weird for me to pair Spyro with Elora but acceptable pairing Ember with Bandit, since when I think of Spyro I now think of the LoS Spyro and the universe surrounding it, but Ember of course only exists in the more carefree games before that.
Yes, right after she told Spyro very callously to get over the death of the most important person in his life. And we don't know how long she and Spyro were hanging out in Avalar after the world was remade. It looked to me like they were just doing a little celebratory loop-de-loop before going back to tell everyone what happened. Still, that's not really an indicator of much and, again, Cynder had ulterior motives for doing both of those things. By contrast, Elora teamed up with Spyro to help him, celebrated at least one victory with him that she wasn't a part of, and treated him like a friend from the start and not just a means to an end.
The callousness was due to poor voice acting as far as I'm concerned, and I didn't mention Spyro and Cynder hanging out in Avalar anywhere; what are you getting at? o_o Even if they only celebrated for one minute and then rushed back to the guardians, it wouldn't still prove anything since rushing to them would be the obvious thing to do regardless of their relationship, not to keep them worrying about their fate.
And yes, Elora treated Spyro well all the way, true. Still, I found Spyro and Cynder's relationship to be more of the mutual kind, and while not perfect since chaining two people to each other rarely ever results with only good things, natural nonetheless and something that would've happened regardless, especially since they were the only ones of their age. I mean, would you rather want to live alone in their situation, only because of the principle of refusing to choose the only option? ;p
I think most Spyro fans have had enough of SxC. It's something that needs to stay in the realms of fanfic. Spyro has gone back to his roots and is now a game for youngsters, a game in which exploring romantic relationships has no place.
As for the fics, I probably won't be reading them. If you'd gotten to me a couple years ago, I might have been interested, but, as I've said, I've had it up to my eyeballs with SxC. It's literally everywhere and nobody is doing anything interesting or unique with it. I've read some of AoH already and I did enjoy the first story but the rest was too bogged down in OCs and really frustrating plot "twists", so I never finished it.
Most Spyro fans have enough of SxC? As far as the canon is concerned, SxC hasn't properly even started yet! How could you possibly have enough of something that hasn't even as much as begun? Sure, there's been 3 years since the release of DotD, but if TEN and DotD supposedly had 3 years between them (as stated by the storyline), then why couldn't the opposite be true and little or no time having passed between DotD and the next possible LoS (as in a game situated in the LoS universe) game?
Then finally about the fics (nearly done with this post, yay!):
While AoH II was about the equivalent of TEN in long, grim violence and frustration, it's regardless definitely worth the read, if for nothing else then for book III and most importantly of all, AoH: Karma and Convexity, which is quite simply one of the best books I've ever read. It's possible to read it without having read AoH I-III, but the references you find if you have read them are enough to make I-III worth reading IMO.
Dark Legacy then is roughly 20 years after the events of DotD, and only has Spyro and Cynder in them from time to time, concentrating on the new generation and a very interesting and enjoyable-to-relate-to character called Lyrith, an albino dragon. Definitely another worthwhile read.
Then there's also Tears of an Oracle and its sequel Residual Darkness, but these star Spyro and Cynder more intensively than the previous books so I imagine you wouldn't be as much interested in them. Definitely do give AoH: KaC (and books I-III) and DL a try though!
OH GOD, seriously I had to break this into 4 posts to avoid the character limit. Hope this is enough "not avoiding your posts" for now! Gonna go soak my typing fingers in hot water now D
