Hey, just out of curiosity and because I don't have the time or energy to check through almost 500 pages for this, is it impossible to tame dragons if you're not a Targaryen?
Also, does anything in particular determine tourney winners? Just since it makes no sense to me for say, a formidable fighter with 30 martial to never ever win or even place in any grand tourneys he's invited to.
Targaryen's (and High Valyrian's) get a bonus, but anyone can do it if they aquire enough Dragonlore and/or build a Dragonpit. And tournament ability is not based off the martial score but on fighting feats.
Martial ability has nothing to do with fighting. A good commander isn't necessarily a good fighter.
Yup, just look at Tywin. Excellent ability to lead, is never found on the front line.
