Rejoice (гет)

Jaehaera IV lit a cigarette, gazing at the statue of her thirteenth great-grandmother, Helaena Targaryen, the Saint of Vengeance and Redemption, across the lake of God’s Eye.
She contemplated the coloured candles that illuminated the sculpted face and ran her fingers over the history book in her lap. The sound of religious hymns in High Valyrian was ominous and, at the same time, put her at ease. Perhaps she really had dragon blood, as her family used to say. Perhaps she was, too, going mad like all the women in her family.

After flicking the cigarette butt out of the window, Jaehaera resumed reading the book – The Dance of the Dragons: The Flame over the Hightower, from King Aegon Targaryen II’s reign to the Sanctification of Queen Helaena Targaryen I.
Based on a true story.
or,
the one where a mother’s grief changed the course of a war.
