(sounds of screaming)
I'm DMing and PCs aren't big enough geeks to come to a message board but can ANYbody edit this thread title to say MASSIVE SPOILERS!
Its a cool story but any player who looks at it will probably have a significant chunk of the metaplot disrupted. I've been very pleased that a lot of the big secrets of the setting (Geleeta's true nature, the Slarecians powers).
Some minor quibiles:
Arcane magic is not Titan Magic. And divine magic is not strictly from the gods.
In each epoch of pre-history a different Titan was ascendent, supposedly. Thulkas' druids were apparently some kind of fire-weilders while Mesos' were probably sorcerors.
I think that Denev is ascendent as an aspect now which is why Scarn is slowly healing and druids are nature oriented. Druids who worship/serve the titans are, in fact, using divine magic.
Arcane Magic:
Mesos had a lot of reality bending powers he touched a handful of races and individuals and they also bear sorcerous blood. This is the origin of socerery in the Scarred Lands.
During his epoch (the previous epoch to the current one) there were also those who studied and understood his magic to the degree that their little minds could. THe druids of Mesos' time were wizards of various sorts. This corresponds, btw, to several of the greatest magical empires which were known of prior to the begining of the divine war. Mesos' epoch when he was rent and scattered about Scarn.
The pervasive nature of "that which was Mesos" is what wizards and sorcerors are now tapping into when they cast spells. There's a bit of metaplot about this in the Divine and the Defeated too.
Arcane magic isn't seen as being Titan magic (though in my game some people think Sorcerors are definitely tainted). However the idea that arcane magic or items are titanic (urg not my best word choice) isn't prevalent, any more than a farmer thanks Madriel for her sun or a traveler Denev for the tree that gives them shade.
Last note: The Slarecians being psionic is actually pretty much stated in the Divine and the Defeated.
Oh and I think Roderick did point something out useful: Maybe people want to talk about their games specifically (maybe without the spoilers...)
