By the way are we planning to participate in a Tourney where? My preferred one if available would be in the Reach since I think it would be one of the bigger one around.
Gulltown does seem to be massive but a few more actions to train our prowess certainly wouldn't hurt, since while i'm sure we could put Criston in the dirt like an unruly squire in the melee, the joust is bit more iffy.
The North is likely out as well, doubt the tourney will be big enough.
The Stormlands could be a good contender but they're on the very end of our progress right before Driftmark, however, the Stormlords would likley be receptive to the show of strength.
The Westerlands would be a big one but not too sure how warmly our win would be recieved.
Iron islands? Yea no, it doesn't seem to hold any of what we're looking for.
The Reach is looking to be the best candidate, it does have a similar issue of our win maybe not being looked upon well, but the Reach has also produced pretty decent guys like Gwayne so who knows?
The Riverlands is also just as strong a contender as the Reach, maybe even better.
