Haco

little fire faerie/sprite who enjoys lightning candles!

perhaps has alternate forms like a familiar?

Intelligentish but not capable of speech. Dog level knowledge but learned how to write its name

It/they/little guy (agender)

Usually very tiny (a couple inches) but size varies with the size of the flame they ignite

Nicknamed Haco by the first person they decided to live with, lighted their candles at night

They've also been called Wick by others which they dont mind!

Haco is warm but not in the way the sun is, with its all-encompassing and nearly suffocating heat. He's a smaller light, one you can hold in your hand. He brightens a room, bringing comfort & offering a path for those lost in the dark.
