Its reasonable to assume that Baela Targaryen was heavily scarred after her fight with Aegon ll, so how would this have effected her marriage potential, she doesn't seem to have much trouble in that regard though since she ended up with a prestigious marriage. Or was that simply due to her immense marriage value, as the cousin to the king and a former dragon rider.
Thanks for the question, Anon.
We don’t know what Baela looked like after her fight with King Aegon II. This is all “The Princess and the Queen” says about it:
Lady Baela stayed with Moondancer all the way down. Burned and battered, the girl still found the strength to undo her saddle chains and crawl away as her dragon coiled in her final death throes. When Alfred Broome drew his sword to slay her, Martson Waters wrenched the blade from his hand. Tom Tangletongue carried her to the maester.
Which is echoed in largely the same way in TWOIAF:
Aegon II leapt at the last moment from Sunfyre’s back, both legs shattering, while Baela remained with Moondancer to the bitter end. When Alfred Broome drew his sword to kill her where she lay broken and unconscious, Ser Marston Waters tore the sword from his grasp and carried her to the maester, saving her life.
The last we hear about her is in 133 AC:
Lady Daenaera was a cousin to Alyn Oakenfist, fathered by his cousin Daeron, who died fighting for him in the Stepstones. A surpassingly beautiful child, Daenaera was but six when the princesses Rhaena and Baela presented her to the king—the last of a thousand maids who had been presented him at the great ball of 133 AC.
No mention is give of her at this time as being visibly burned or scarred. While that could be the result of TWOIAF’s overall skimping on many details, it could also mean that whatever burns or wounds she had taken in the fight had healed by the time she was 17.
As for her marriage … as we’ve seen in the main series with poor Lancel, even a physically infirm and broken individual can be a potent marriage pawn for a dynasty looking to secure possessions. Baela had a strong claim to Driftmark in her own right, as the daughter (and probably elder daughter) of Corlys’ daughter Laena; between the daughter of a a daughter and the bastard-born (but legitimated) son of a son, there might have been questions as to who should succeed as Lord (or Lady) of the Tides. If Baela married Alyn, though, their potentially competing claims could be combined: Baela and Alyn’s children would be (legally) grandchildren of both of Corlys’ children, twice-over heirs to Driftmark. Given that she had unnamed (and unnumbered) children with Lord Alyn, I think it stands to reason Baela was reasonably physically recovered from her dragonback battle by the time of her marriage, even if she still appeared burned and/or scarred.
