Why aren't any epic level good heroes helping OotS if the world may end?

[TooSoon]

One would think that if the entire world's fate is at hand, really high level people would come out of the woodwork and help crush Xykon and One eye. Apart from the "then it wouldn't be OotS adventure" is there a reason why they are not getting more help? Are they the only high level heroes- I'm pretty sure they are not. I get the need for secrecy, but when you are down to one gate and the bad guy is there before you, you should get more help than the couple of paladins and a mid level dwarf priest, right?

It's like a reverse "throw the ring in the lava" situation- where's the rivendell meeting putting together a super team?

It's a fair question. The instinctive reply is "well, this is a low levelled world"... and that's kind of true. On the other hand, it's also not. For instance, V's master would be, what, level 16+ at least to be an Archmage? Assumedly higher, since I doubt they get called Archmage for having 1 level in it. Similarly, there have been other Archmage's an wizards in the past (like Fyron) who are assumedly high enough level to help a lot. The elves have a country of their own too, which must have high level characters. Then consider the Familicide spell. Did you see how many Black Dragons were killed? The corollary of that is there should be similar numbers of good dragons who want to help save the planet (and even the evil ones don't want it to be destroyed). The Ancient Black Dragon was a 32-33 HD monster with at least level 17 Sorcerer abilities. It was more powerful than the entire Order is now. The good versions of such Dragons sure would come in handy right now. Even the Evil ones aren't likely to interfere to stop them, they don't want to be destroyed after all. There have also been a few other characters, some joking ones, some serious, who have appeared on panel and would probably be a big help. Ok, they don't all know about it, but many of them (such as V's master) could be easily informed, and by this point High Level Dragons watching over humanity should have enough clues something pretty serious is going on (and some of these people could be reached out to for help).
