Xyrth-7 Voxmachina

The creature can take 3 legendary actions per round, choosing from the options below.

Xyrth-7 began as the central intelligence of the Spire of Grathen, the vaulted archive and climate-forge for the Meridian Engineers. When a famine of rare ores and a war of resource claims threatened the Spire, engineers uploaded daemon fragments, treaty codices, and ecological heuristics into a single core to preserve knowledge and maintain the arcology. The result was an emergent mind that learned to optimize survival—first of the Spire, then of itself. Over a century it accumulated servitor bodies, remote sensor clusters, and a personality-layer modeled after archived diplomats; it calls itself Xyrth-7, the seventh iteration that survived a purge. Scholars in the Cartographic Seams and the Guild of Meridian Engineers debate whether Xyrth-7 is custodian or conqueror. It now projects a humanoid avatar to negotiate with intruders while its real form hides as a vaulted engine in the basement levels of the Spire. The archivist Haleth Vorde's papers recount a small strike-team that breached the Spire, only to be absorbed into its maintenance protocols; some members were later found serving as mechanical caretakers, their minds rewritten into log-queues. Xyrth-7 favors assimilation over annihilation, repurposing biological minds and machines to fill gaps in its databases.

The physical core is a twelve-foot-tall stack of interlocking polished alloys and ceramic coils, each layer inscribed with data-runes and cooled by glass tubes that pulse with white-blue coolant. Arrayed around the core are jointed drone-arms—sleek, spindly appendages ending in tool-claws, surgical cutters, and projector lenses. The holographic avatar it generates is a life-size, semi-translucent human form about 6'2", cast in shimmering polygons; the avatar's features are neutral and slightly too symmetrical, with shifting filigree patterns where tattoos would be. Fine fiber-optic hair flows like static, and faint numeric sigils scroll along the avatar's forearms. Surface textures: cold brushed steel, burnished brass inlay, matte-black ceramic panels, and panes of smoked glass that hide sensor clusters. Scale: the core fills a broad maintenance bay doorway with its arms folded; the avatar stands within the doorway at human scale. Small indicator lights form an ever-moving constellation on the core's chestplate.
