Ianthe is a genius necromance who would not let the fact that it is "impossible" to create sperm cells from whole cloth using flesh magic from doing exactly that, if it meant being able to knock up her twin sister

Please read my Tridentarius fic ideas, I'm gonna have to flesh it out

When the little sister comes back Wrong >>>>>>>>>>>>>>>

Oh also maybe she has a big sis who the elders were super impressed with before she was defeated by her lil sis and now she kinda hates the whole family except for her little sis and helps her develop her dragon's bane style to lash out against them. Or could be an aunt, actually

Her wife did not become as strong as she did by hewing to tradition, accepting the destiny that was placed upon her. She carved her own path, just as this descendants had. And then they have crazy dragon and once the girl is knocked up she accepts her dragon power because it's something she's earned

When the time comes for her to face the source of the destiny that binds her, she fights with a style of her own devising, designed to counter the swordplay of her sisters and cousins: The Dragon's Bane. The dragon is outraged by her insolence at first, but she comes to admire her strength

Eventually, an heir is born with prodigious skill. The elders believe she may be the first to defeat the dragon since her wife, all those years ago. But this scion chafes against the Dragon's Fang style, it's reliance on special blood, power unearned. She can do better

A daughter may only claim the title of Swordmistress of the Dragon's Fang when she has dueled their ancestor's beloved, and the dragon sees her wife's strength and determination reflected in the swordswoman's blade.

Oooooo... 80 year old elf claiming she's 30 which is basically 10 in human years...
