Pepper

Wow, more descriptions...

Pepper is technically a pixie cat from Idyllia.  Which begs the question, "What is Idillya?"

Idyllia is a kingdom in another realm, ruled by three queens.  They are connected to our world, through an interdimensional gate.  They are usually at peace, but are in cyclical conflict against draconic creatures called Nightbringers.

The Nightbringers are not easily defeated.  The only way to deal with them is to push them through the interdimensional gateway, and into the other dimension.  The journey weakens the Nightbringers, but in time, they recover their strength, and they become a menace, again...

Then, it's time to push them back.  The cycle is usually twenty years...

The gateway to Idyllia is in the far north, in Alaska.  The gate opens up when the auroras flare, near a tiny city state called Mathura.  As such, the people of Mathura are also in war with the Nightbringers, each time they cross through the gate, from Idyllia and into our world.

Mathura, Alaska, was ruled by a chief-king and his queen.  They were kind, and fair rulers, greatly beloved by their people. But in the last attempt to push the Nightbringers through the gate, they died.  They left a young son behind.  His name is Dhruva.

The rulers of Idyllia have the safety of Mathura, and the safety of Earth, as one of their top priorities.  Idyllia depends on Earth.  When the earthly leaders of the war against the Nightbringers were killed, Idyllia's third Queen came to Earth, to help in the fight.  To do so, she reversed in age, and left her crown-horn behind, to join the fight in Earth, as a child princess.  Her name is Lena.

Her powers weakened by her not being able to use her Queen's crown, she was given a sacred weapon, and brought with her a guardian pixie cat, of unimaginable power.  The pixie cat's name is Pepper.

There's your explanation. ^^
