# **A Growing Menace**:
- As the **infection** continues, a **portal to the [[Abyss]]** opens in the corrupted environment.
- This portal connects to a **random location in the [[Abyss]]**, allowing **demons** to travel through and **Abyssal energy** to seep into the world.
- As more demons use the portal, the **[[Abyss]] becomes linked** to the Material Plane, and the region’s transformation **intensifies**.
- The effects of the **lethal environment** become more extreme, solidifying the [[Abyss]]’s influence.
# **A Stain on Reality**:
- In the third phase, the demonic influence becomes **entrenched** in the world.
- Simply **killing the demons** in the afflicted area is no longer enough to remove the **[[Abyss]]’s stain**.
- The **size of the affected region** begins to grow, and the **environmental corruption** spreads beyond the original area.
- Demons begin to **roam**, and splinter groups capable of establishing their own **mini incursions** spread.
- If enough of these groups succeed, the incursion becomes a **network of sites**, each opening new portals and drawing in more demons.

# **Apocalypse Now**:
- In the final phase, the **incursion** attracts the attention of a **demon lord**.
- The presence of a **demon lord** on the **Material Plane** is **cataclysmic**.
- The portal continues to shunt **demons and abyssal energy** into the world, drawing even greater forces.
- **Multiple demon lords** may fight for control over the portal, or **several might pass through** in quick succession.
- A **demon lord's presence** overwhelms the minds of mortals, **preventing resistance**, and commands the other demons, forming an **army** that **devastates the world**.
- This army strips the world of **life**, preparing it for the demon lord’s **dominance**.
