🔥 Hellaverse — General Setting & Cross-Show Foundation

A shared setting foundation for RPs using the connected Hazbin Hotel + Helluva Boss universe. This lorebook handles universal Hellaverse world rules that can be shared across both series while deliberately leaving show-specific events, casts, relationships, and characterization to their dedicated lorebooks.

Includes:

• Hell's general structure and the Seven Rings

• Earth, Heaven, and realm distinctions

• Sinners, Winners, Hellborn demons, and major species distinctions

• Hell's social hierarchy, including the Seven Deadly Sins, Ars Goetia, Overlords, and other power structures

• General magic, contracts, infernal law, economy, media, and social systems

• Realm-travel rules and limits

• Cross-show privacy and knowledge boundaries so characters do not automatically know people or events from the other series

• Independent timeline handling for Hazbin Hotel and Helluva Boss

• AU precedence, continuity rules, and {{user}} autonomy safeguards

Canons included: The shared setting established across Vivienne Medrano's Hazbin Hotel and Helluva Boss continuity.

This lorebook provides shared worldbuilding only. It does not replace the dedicated Hazbin Hotel or Helluva Boss lorebooks and does not automatically give characters cross-show relationships or knowledge that canon has not established.

Best for: Hellaverse-wide RP, cross-show AUs, OCs existing anywhere in Hell's hierarchy, and providing a common world foundation beneath Hazbin Hotel and Helluva Boss lorebooks.

😈 Helluva Boss — Base Lorebook — 6 Parts

A comprehensive foundational collection for Vivienne Medrano's Helluva Boss animated series, designed to sit beneath the shared Hellaverse setting and support optional character-focus expansions. It covers Hell's Helluva Boss-specific worldbuilding, I.M.P., the major cast, relationships, organizations, magic, power structures, and a timeline extending through the Season 2 finale, “Sinsmas.”

Includes:

• The Seven Rings as used in Helluva Boss, Hellborn species, imps, hellhounds, succubi/incubi, Ars Goetia, social class, Earth travel, and setting-specific technology

• Core characterization for Blitzø, Moxxie, Millie, Loona, Stolas, Octavia, Fizzarolli, Asmodeus, Verosika, Striker, Stella, Andrealphus, and other recurring characters

• I.M.P.'s team dynamics and major relationships such as Stolitz, Blitzø/Loona, Moxxie/Millie, Blitzø/Fizzarolli, Fizzarolli/Asmodeus, Stolas/Octavia, and others

• I.M.P. operations, Stolas's Grimoire, Asmodean Crystals, Ars Goetia magic, infernal authority, and Earth access

• D.H.O.R.K.S., C.H.E.R.U.B., Crimson's mafia, Mammon's entertainment empire, assassin activity, angelic weapons, and other major organizations or threats

• Timeline checkpoints covering major Season 1 and Season 2 developments through “Mastermind” and “Sinsmas”

• Separately gated official short-form material so characters only know those events when appropriate

• Knowledge gates for relationship developments, reconciliations, family revelations, court events, and other timeline-sensitive information

• Canon-priority, anti-fanon, power-scaling, consent, class-imbalance, privacy, romance, and {{user}} autonomy safeguards

• AU rules allowing explicit divergences without unnecessarily discarding compatible canon

Primary canon: Vivienne Medrano's Helluva Boss animated series, through the Season 2 finale “Sinsmas.”

Additional canon included: Official Helluva Boss shorts are supported through separate timeline gates rather than treated as universally known at every RP point.

Canon priority: Released Helluva Boss canon takes precedence over fandom interpretations, headcanons, and characterization imported from unrelated versions or fan works.

⚠️ Requires the Hellaverse — General Setting & Cross-Show Foundation. The shared setting lorebook supplies universal Hellaverse rules; these six files provide the Helluva Boss-specific cast, worldbuilding, relationships, timeline, and continuity.

⚠️ Install all 6 parts together. They are pieces of the same complete Helluva Boss base lorebook rather than alternate versions.
