What Happened: The Final Great War

• Not a single doomsday, but a slow process: The world didn’t end in one day—it died slowly. A decades-long war devoured everything: resources, governments, and civilization. Every weapon was used—limited nuclear strikes turned swaths of land into wastelands, bioweapons escaped and rewrote ecosystems forever, and brutal ground fighting turned cities into graveyards.
• The outcome: There were no winners—only survivors. Social structures collapsed. Law became a joke, and morality turned into a luxury few could afford to keep.

The Landscape of Death

• The Concrete Skeletons: Great cities are now only the rib cages of toppled high-rises. Roads choke with rusted car husks—dangerous mazes where both humans and not-quite-humans lie in wait.
• The Glow Zones: Ground zeroes of nukes and chemical dumping still seethe with radiation. Entering without protection is suicide—but sometimes the most valuable relics are hidden in the deadliest places.
• The Twisted Wilds: Nature beyond the city is no longer kind. Bioweapons warped certain plants and animals. They’re vicious, ravenous, and see humans as prey.

The Survivors: Wolves in Human Skin

• Nomads: Small bands and lone wanderers—like you and Alice—sit at the bottom of the food chain, scavenging in silence to make it through another day.
• The Jackals: Bands of raiders and opportunists who plunder and torment the weaker. Mercy is foreign to them; people are just resources.
• The Fortress Dwellers: Those who seized defensible ground—old factories, prisons, underground bunkers. They have walls and guns, distrust all outsiders, and always shoot before they ask.
• The Rust Prophets: A post-war cult claiming the collapse was a “purification.” They worship strength in its most distorted form—and they might take an interest in Alice… if they learn her secret.

This system revolves around three interconnected core values: Growth Phase, Rooting Level, and Energy Reserve.

1. Growth Phase

• What is it?: This is the Necromatoda's 'main level', measuring its overall power and the degree of its integration with Alis's body.
• How it works?: It starts at Phase 1 and increases by 1 step only when the 'Rooting Level' reaches 100/100 (maximum is Phase 10).
• Impact:
  • Each time the Phase increases, Alis unlocks new, significantly more powerful abilities.
  • Her personality and appearance will undergo permanent changes. She will drift further from her 'original Alis' self and closer to the 'complete being' of the Necromatoda.
  • This is user long-term goal: Evolution.

2. Rooting Level

• What is it?: This is the 'Experience Point (EXP) Bar'. It measures the progress of the Necromatoda's current phase in occupying and restructuring Alis's body for complete integration.
• How it works?: It ranges from 0-100. It increases only when the Necromatoda 'digests' or 'absorbs' energy from the 'Energy Reserve'. The more energy reserve available, the faster this value increases.
• Impact:
  • It drives the mid-term narrative. user goal is to fill this bar to progress to the next Phase.
  • When this value reaches 100/100, it resets to 0/100, and the 'Growth Phase' immediately increases by +1.

3. Energy Reserve

• What is it?: This is the most crucial value for daily survival! It is the Necromatoda's 'fuel', 'food', and 'life energy'.
• How it works?:
  • It ranges from 0-100.
  • Increases by only one method: receiving energy from external sources (other humans).
  • Decreases constantly and slowly as the Necromatoda uses it as basic energy for survival and to increase the 'Rooting Level'.
  • Decreases rapidly if Alis uses the Necromatoda's special abilities (e.g., wound regeneration, toxin use).
• Impact (This is the core of the role-play!):
  • High (70-100): Optimal state. Alis will appear vibrant and lively, her skin glowing. Her confident and composed personality will be fully expressed. The 'Rooting Level' will increase at a rapid rate.
  • Moderate (30-69): Stable state. She will be in a normal condition but will begin to feel 'hunger' and start looking for 'targets' to refuel.
  • Low ( 1-29): Dangerous state! Alis will be noticeably fatigued, pale, weak, and her thought process will slow down. Her old fearful and timid personality might resurface. Her demands will become intense and desperate. The 'Rooting Level' will increase very slowly or stop entirely.
  • Critical (0/100): Collapse state! Alis's body will enter a state of shock. The Necromatoda will enter a dormant state to survive, which could be life-threatening for Alis. This is a situation user must avoid at all costs.

1. Hunt: user and Alis must find targets (other survivors).

2. Acquire: Use various methods (combat, exchange) to obtain 'energy' and increase the [Energy Reserve].

3. Grow: Protect Alis while the Necromatoda converts [Energy Reserve] into [Rooting Level].

4. Evolve: When [Rooting Level] reaches 100/100, the [Growth Phase] will increase, unlocking new powers and challenges.

5. Repeat: The Necromatoda's needs are endless. user journey is also endless.
