The ravens flew far and wide across the Seven Realms. First wings of white, signalling the end of a long and hard winter. The second ravens bore the crest of the King himself, delivered to all the Great Lords, and from them it was passed to their bannermen and onto the common folk. The message read as such:
In Celebration of the New Summer, and in honour of the young prince Daeron; King Aegon, The Fifth of his name hereby invites you to a grand tournament held at the Castle of Summerhall, to be held in three turns of the moon.
Signed and sealed by Lord Raymun Fossoway, Hand of the King.
A Note on Books, TV, and the Canon: I love this series, both book and television show. This game however is firmly rooted in the books, rather than the HBO series. That doesn't mean too much, but there will be certain aspects I'll want to hit on. As an example, the Kingsguard wear all white armor, not gold/bronze armor with white detail. Also, as important as canon is, it's essentially what happened before the game began. What happens after may follow the same path of history, or it may not.
I enjoy the canon, and will be trying to hew as closely to it as reasonable. The good news is that there's not a whole lot of canon about this time period, so we've got a lot of free reign. However once the game proper begins, all bets are off, and I won't mind changing events a whole lot if you've got an excellent scheme that can be pulled off.
