In Ascara Eastern physiology, bloodline inheritance follows predictable but highly variable patterns determined by the relative potency of paternal and maternal ancestral essences at conception and throughout development.
Single Bloodline (Most Common Outcome)
The majority of Eastern offspring present with two ancestral essences at birth. One essence rapidly establishes dominance. The weaker essence is progressively metabolised and re-absorbed by the dominant line during childhood. By bloodrite (age 21), only the dominant essence remains detectable. Individual classified as single-bloodline permanently.
Dual-Potential Births
Approximately 8–12% of Easterner births demonstrate near-equal potency between paternal and maternal essences at birth. These neonates are flagged immediately for intensive longitudinal monitoring.
Both essences must remain in dynamic equilibrium throughout development. Deviation >15% potency differential triggers irreversible absorption of the weaker line and reversion to standard single-bloodline trajectory.
At bloodrite, four documented outcomes occur:
Complete Devouring (≈60% of dual-potential cases)
One essence achieves total dominance during the ignition phase and metabolically consumes the rival essence entirely. Residual spiritual fragments <0.01%. Individual reverts to single-bloodline phenotype with no latent markers. No breeding advantage.
True Dualiner (≈5% of dual-potential cases)
Both essences ignite simultaneously and establish stable co-expression. Meridian capacity increased 1.8–2.3× baseline. Example: Lord Darian Long — active Long + Zhao markers. True dualiners are classified strategic-level assets; unless the individuals are from one of the eight celestial clans, marriage contracts often require imperial oversight.
Veiled Dual (≈35% of dual-potential cases) Primary essence manifests fully; secondary essence collapses to trace latency (0.1–10% residual activity). Individual cultivates as single-bloodline but retains recessive markers in germline. Clinical designation: Veiled Dual. Highly prized in long-term breeding programs due to the theoretical possibility of recessive re-emergence in descendants (unconfirmed in 1,042 years).
Maternal Dominance Reversal (<1% overall, variable by parental potency gap)
Maternal essence manifests as primary despite paternal clan investment. Immediate legal transfer of the individual to the maternal clan is required under celestial statute. Paternal clan forfeits all claims and invested resources.
Tri-Lineage and Higher
No confirmed survivable cases in recorded medical history. Attempted tri-manifestation uniformly results in catastrophic meridian rupture and death within minutes.
Strategic Implications for Celestial Marriage Policy
Intra-celestial unions: lowest reversal risk, moderate true-dualiner yield. Celestial–high noble unions: elevated Veiled Dual probability but significant risk of total child loss via maternal reversal.
All celestial clans maintain actuarial tables balancing short-term power projection against multi-generational bloodline security.
