Well it is in the very early stages, so nothing is set in stone or ready to post an interest thread. The idea involves a group of reasonable newly Exalted Solars who have been dreaming about a location in the jungles of the southeast. Said location being the hidden tomb of a Circle slain shortly after the Usurpation. Said Solars were buried in the tomb they had prepared for their eventual demise (something they did not expect for many centuries to come) so as not to anger their ghosts. However, with the Usurpation this Circle who was not at the great convocation made some last minute tweaks knowing their ends were drawing near.
Fate and circumstance would lead the newly minted Solars to arrive at said location and almost exactly the same time---because without coincidence most epic fantasy just would never be. The resonance of this exact set of Solar Essenses being the "key" needed to unlock the tomb revealing some goodies and secrets for the Solars to ferret out and from there said adventure would ensure.
And no, said Circle need not be a Perfect Circle.
