The Nine Realms

The Yggdrasil ecosystem organizes all projects into Nine Realms, inspired by Norse mythology. Each realm has a distinct purpose, color, and identity within the architecture.

Realm Details

Asgard — Core Technology

The foundation realm. Houses the main infrastructure projects:

  • Yggdrasil CLI — Command-line interface for the ecosystem
  • REGLAS_YGGDRASIL.md — The global rules and conventions file
  • Core libraries — Shared utilities and frameworks

asgard projects define the standards that all other realms follow.

Vanaheim — AI Agents

Where the intelligence lives. AI-powered agents, bots, and personality systems:

  • Lilith v2.0 — The flagship anime/cyberpunk neon personality engine
  • Discord/Telegram bots — Agent interfaces for community interaction
  • Prompt libraries — Character definitions, system prompts, response patterns

vanaheim projects are autonomous systems that perceive, reason, and act.

Alfheim — UI Prototypes

The realm of visual creation. Frontend projects, design systems, and interfaces:

  • BrierStudios Landing — The main website at brierstudios.com
  • Docs site — This documentation hub at docs.brierstudios.com
  • Design prototypes — Experimental UIs and visual concepts

alfheim projects prioritize aesthetics and user experience.

Svartalfheim — Knowledge

The forge of documentation. Docs, wikis, and reference materials:

  • Architecture docs — System design and decision records
  • API references — Command catalogs and integration guides
  • Tutorials — Step-by-step guides and onboarding materials

svartalfheim projects craft the knowledge that powers the ecosystem.

Muspelheim — Active Dev

The crucible of creation. Work-in-progress projects and active development:

  • Feature branches — Unreleased changes being actively developed
  • Hot repos — Projects with daily commits and rapid iteration
  • Staging environments — Pre-deployment testing grounds

Projects in muspelheim are not yet stable. They move to other realms upon release.

Niflheim — Resources

The cold storage of assets. Datasets, media, and raw materials:

  • Training datasets — LoRA reference images and captions
  • Media assets — Icons, SVGs, fonts, textures
  • Configuration files — Shared configs pushed across projects

niflheim projects are rarely modified but frequently referenced.

Helheim — Archive

The graveyard. Deprecated, abandoned, or completed projects:

  • Legacy repos — Old versions kept for reference
  • Deprecated tools — Replaced by better solutions
  • Completed experiments — One-off projects that served their purpose

Projects in helheim are no longer active but preserved for history.

Jotunheim — Massive Projects

The realm of giants. Large-scale monorepos and enterprise projects:

  • Ecosystem consolidations — Multi-package monorepos
  • Enterprise systems — Large, multi-team projects
  • Platform services — Shared infrastructure at scale

jotunheim projects are characterized by their scope and complexity.

Midgard — Personal Apps

The human realm. Personal utilities, scripts, and daily tools:

  • Automation scripts — Personal workflow automation
  • Utility apps — Small tools for daily use
  • Config dotfiles — Personal development environment setup

midgard projects are practical, personal, and pragmatic.

CLI Realm Aliases

Each realm has a short alias for the Yggdrasil CLI:

# List all projects in a realm
ygg asgard list
ygg vanaheim list
ygg alfheim list

# Create a new project in a realm
ygg muspelheim create my-project

# Move a project between realms
