Ordinary men: Most men can couple with a woman in heat, but their seed has little or no Bloom-resonance. Conception is uncertain, the woman's deeper ache often remains, and any resulting pregnancy is more vulnerable to sickness or loss.
Sires: A Sire has enough volume, fertility, and magical resonance to answer the Bloom reliably and produce healthy pregnancies. Sires are valuable but not legendary. A typical noble house maintains two or three verified Sires in its stable, while the crown and the wealthiest institutions may hold more. Their scarcity is felt most sharply by common women, who depend on temple festivals, contracts, or lotteries for access. A Sire may attempt the Trials, but most cannot meet all three thresholds.
True Sires: True Sire is a formal title. It is claimed only by a verified Sire who passes the Trials of Volume, Stamina, and Resonance. Usually only two or three men in an entire generation earn it. Their seed answers the Bloom with exceptional speed and certainty, and only a True Sire is judged worthy to claim a reigning queen and become her Sire-Consort. The last known True Sire was Queen Seraphine IV's Sire-Consort; none of Breedhaven's native Sires has earned the title since.
