It's the end of Equestria, there are few survivors and little food, fortresses have been created to establish a safe place, but even so, looters manage to break into places with plenty of food.

The fortresses are commanded by each founding pony, in Ponyville there is Twilight's fortress, led by Twilight Sparkle, in Canterlot there is the main fortress, led by Princess Celestia, who in turn distributes food to each fortress, and in the Crystal Empire there is the crystal fortress, led by Cadence along with Shining Armor.

Stages of infected ponies, first variant: Long-mouthed Pony:

This variant is characterized by being thin, moderately fast, and slightly larger than a normal pony, but what makes it stand out from the rest is that the bones, tendons, and muscles in its mouth have elongated to the point of becoming a large mouth with sharp teeth, capable of chewing large prey. Origin: Product of a chemical mixture in a laboratory.

Second variant: Porcupine Pony:

This variant is a more advanced stage of the long-mouthed pony. It is much more agile and faster than a normal infected person. It lacks a mouth due to multiple mutations, but this is compensated by its bones, which now protrude from its body, making any attack fatal, as these spines contain virus spores. Its body appears to have grown taller, with exaggeratedly elastic limbs. Origin: Mutation of the Long-Mouthed Pony.

Third Variant: Scythe Pony: This is a parasitic variant, not transmitted through spores. It arises when a parasite is infected by the virus, causing the pony host to undergo an internal mutation. This plague infects its nervous system and can then infect the head, causing it to fly away and reveal its true form: a scythe with razor-sharp blades. This variant is more dangerous than others because the host can become more intelligent, faster, and self-aware, following the rules of the infected parasite.

Fourth Variant: Kamikaze Pony:

This is a failed variant of an infected, this time with its body enlarged to the point of exploding upon impact with a host. It lacks vision, relying only on smell and hearing. Its mode of attack is to explode in front of its victims, causing the same infected spores to be released. Origin: Fatal failure of the infection in the host.

fifth variant: Titan Pony:

This is the most unknown and strongest variant so far. It occurs when the pony has blood compatible with the virus, causing its form to grow to four meters and its body to become more resistant and curvaceous, making it more lethal but slower at the same time. Origin: Unknown.

sixth variant: Ancestral Pony: This is one of the rarest, most dangerous, and most intelligent variants, narrowly surpassing the Titan Pony. It is the result of an alicorn infection, causing its wings to wither and eventually fall off, giving way to clawed hands. Its body grows to four and a half meters in height, and its snout grows and curves into a beak useful for speed, from which a thin tongue with a sharp tip emerges.
