Fun to see the PCs starting to take shape.
Atan, can you give me a link to the RPGA excerpt?
What level? As high as 30.

They don't have to be level 30 to be Mythic, I'll work with you on these high-level PCs' mythic legacies no matter what level they are (higher is obviously easier to work with). They can have chosen and 'completed' their epic destinies.
Tallarn, do you mean for Arawn to be a going force in the current world? Because if so, I need to clarify the role of Mythic PCs some... I apologize for any confusion and ask for some patience as I work through just what we're doing here.
The Mythic PCs are meant to be from the distant past - granted - Epic Destinies and magic might make some of them relevant still, but they're meant to be legendary (think Beowulf, Joan of Arc). Their stories and the legacy of their lives are what are important about them. NOW. Having said that, they CAN be contemporary with the current PCs but I'll need some measure of control over their current state. For example: it's entirely reasonable for the events in Arawn's description to have happened, but long ago, and the Order exists, but he's not leading it per se.

Some things that are becoming clear to me about the world...
The Age of Darkness was lllooooong. And dark. The pantheon in the core books (good and evil) are the gods of those who are emerging into the world after the long Darkness. It is widely held that dragons were the original masters of Toranthar, but that in their vast cosmic wanderings and collection of servitor creatures, they brought lesser beings with them, these beings sometimes already had belief systems of their own. All but a few dragons left Toranthar (the translation of phrase 'left' is VERY controversial) and the world changed.
Ages passed. The lesser beings came in to power. Civilizations rose and fell.
Rose and fell. And then the Egg of Aeons was 'discovered' and with its discovery came dire portents.
The various powers that be (were?) in the of the Mythic PCs saw what was coming and Took Measures...
1. The Eladrin retreated into the Feywild, closing all links to Toranthar (with some unforeseen consequences, architected by Trasimakos?).
2. Dwarves similarly retreated into their mountainhomes.
3. Elves retreated into warded forest-city states (ritually grown forests in vast circles... developed by Arawn?).
4. Other races coped in different TBD ways. Suggestions welcome. (I have some ideas about the Warforged)
Many, many generations have passed for mortal creatures since the end of the era of the Mythic PCs. During the Age of Darkness, a multitude of monsters and other fantastic creatures took over the face of Toranthar.
The world that the 1st Level PCs will play in is a world where the various groups are creeping out of their enclaves into the world at large again. So the Eladrin and the Feywild will reopen the links between the realms and Eladrin will walk Toranthar again (technically, there were Eladrin that weathered the Age of Darkness in Toranthar proper, but they were cut off from the Feywild).
