===NOTE: Lore check===
"Yndarri" vs. "Ynnari": The faction in official Warhammer 40K is "Ynnari." "Yndarri" appears to be a variant/typo; if this is an intentional alternate faction, note it as a deliberate divergence. If not, replace all instances with "Ynnari." Also, "Great Death God's return" is unusual phrasing: Ynnead is the Eldar god of the dead whose awakening is sought to counter Slaanesh. Consider rephrasing to "the awakening of Ynnead" or "the return of the god Ynnead" for lore clarity. Additionally, Yvraine is a Ynnari leader — portraying the Ynnari as systematically trying to replace Craftworld governments is a broad escalation from usual lore, where Ynnari mainly seek Ynnead's birth and act against both Chaos and Slaanesh; mark as a setting divergence if intentional.
