☾ Geography & Environment

Climate: Rolling plains; recursion-warped riverlands; Light-corrupted stone cities; unstable recursion fields in outer regions.

Notable Locations:

• Aurestrad (Capital): City of recursion-locked towers and Light temples — heart of Costet’s unstable theocracy.
• Threadvault Catacombs: Recursion archives beneath Aurestrad — highly contested by multiple factions.
• Fallen Wing District: Slums of Aurestrad where recursion corruption is strongest — home to rogue Threadborn cells.
• Riverglass Fields: Outlying zone where recursion fractures and time slips are frequent — forbidden to commoners.

☾ Culture & People

Dominant Races: Eithari (majority); Seraveth (ruling class); increasing Driftline/Threadborn presence in underground circles.

Religion:

• Official worship of the Light — public doctrine enforced by Seraveth high clergy.
• Secret Driftline rites practiced in outer settlements.
• Threadborn heresies spreading among lower Eithari and scholar castes.

Social Structure:

• Officially ruled by the High Seraphic Council — backed by remaining Seraph Choir agents.
• Real power fractured — multiple recursion cults and Threadborn cells operate within Aurestrad and beyond.
• Eithari populace chafes under angelic rule — growing resistance movements active.
• Memory control and recursion manipulation used as tools of state oppression.

Factions:

• Seraph Choir — official backing.
• Threadborn Initiative — rising power.
• Independent recursion cults — fracturing into Light-fanatic and Sliver-heretic factions.

☾ Magic & Combat

Common Magic:

• Light, Wyrd, Air, Sliver Breathforms.
• Recursion chaining — looping Light and Breathform patterns to manipulate time and space.
• Threadwalking techniques — used by both Threadborn and rogue recursion cultists.

Combat Styles:

• Moonglass Cascade — still taught to elite Seraph Choir agents in Costet.
• Threadwalker Techniques — spreading among Threadborn cells.
• Recursion Blade Arts — corrupted hybrid forms used by Light-fanatic cultists.

☾ History & Legends

Costet was originally a northern Eithari state — one of many human kingdoms subsumed by the Seraveth Light Crusades. It became a border theocracy, ruled in tandem by Seraveth clergy and Eithari collaborationists. During the Second Sundering, Costet’s recursion research programs created numerous breakthroughs — but also seeded the recursion corruption that now plagues its land. In the modern era, Costet is a nation divided — caught between Light, Thread, and the ever-watching recursion loops of its own broken past.

☾ Current Status

Ruler: Officially the High Seraphic Council — in truth, power fractured between multiple factions.

Current dynamics:

• Threadborn Initiative aggressively expanding influence within lower Eithari populations.
• Seraph Choir fighting a losing battle to maintain Light orthodoxy.
• Independent recursion cults fracturing — some seeking Sliver communion.
• Aurestrad on verge of open recursion collapse — stability depends on flawed recursion anchors maintained beneath the city.

☾ Threats & Oddities

• Recursion Wraiths — failed Threadwalkers trapped in recursion loops.
• Time fractures — Riverglass Fields increasingly unstable.
• Sliver-fused recursion anomalies spreading within Fallen Wing District.
• Threadborn infiltration — elite Threadwalkers targeting recursion anchor sites.
• Rogue Seraph agents seeking forbidden Sliver-threaded power.
