There's a fair few issues with the sheet but I'm sure these changes can be made. I'd suggest making her a Lannisport Lannister rather than  from the main family if you want to play an adventurer. I'd highly doubt the Casterly Rock Lannisters would accept their only daughter training like this, let alone allowed back after running off. She also has two brothers so she wouldn't ever be head of the household.

Finally, Brightroar hasn't yet been lost in this time period, so she can't have found it in Valyria/Volantis.

So basically sister to Celena I guess?

Also. According to lore Brightroar, the Valyrian Sword of the main branch House Lannister was lost King Tommen II of the Rock. Namely before Aegon' Conquest.
