So Mune is a Golem?

Yep, he's made of stone and magic with some bits of foliage here and there. He's quite small though, not like the big, strong kind that comes to mind.

who made him?

A powerful wizard named Luneris. He ment to make an empty shell to use as a new body, but ended up making Mune instead.

Is he dead?
BTW how does he taste to Sol?

yep, he's alive. And for Mune's taste, he tastes like apples.

Sounds nice

What's Mune's relationship with Luneris?
Does Mune taste like apples because of the plants or is there some weird magic thing where Sol can taste his spirit?
What does a day for Mune and Sol usually look like?

Mune and Luneris are enemies. Luneris believes that all non-magic life, such as humans or dogs, is unnatural and wants to purge it. Mune doesn't share these beliefs, instead believing all life is sacred.
Mune's apple taste comes from the plant part of him.
Mune and Sol both run a potion shop. Mune grows the herbs and brews most of the potions while Sol hunts monsters for valuable parts and picks up any extra slack in the shop.

So is Luneris a Golem too then?
Makes sense
So Mune is kinda like a HouseHusband (I know they're not married but still) my kind of relationship

Luneris is actually an anthropomorphic moth like creature called a mothid, which are very skilled in magic. by magical creatures, I ment creatures that have magical capabilities, such as the ability to cast spells. Sorry for the misunderstanding.
As for Mune being a house husband, that's pretty on the dot now that you say it.

It's okay,
How does magic work in your world?

There are 10 different magics in Rattackia. Life, Water, Earth, Air, Fire, Frost, Elecrtic, Sound, Light, And Void. all of these magics are created through 10 crystals created by the gods. There are also 2 pseudo magics, Chaos, and Waste. these magics are not considered to be true magics, as they have no crystals producing them, instead being created as a byproduct of using up magical energy.
Usage of magic comes in many shapes and forms. Bards create songs that harmonize magical energy, wizards draw runes in the air, and some creatures come with spells as a part of their anatomy and can use it with like how someone can move their leg by sending the messagefrom their brain to their body. An example would be a dragon breathing fire.

cool

where are these crystals?

Scattered across the world. The crystal of life is at the very top of the tree of life, while rhe crystal of void is deep underground, guarded by the tree's roots. earth is in a giant underground desert with a mini sun at the top of the cavern constantly beating down on it.
fire is deep in the bowls of an active volcano.
water is far away from any land at the center of the ocean with an underwater city surrounding it.
Both electric and sound are in a cyberpunk city.
air is kept on the back of a massive sky whale with a city on its back.
Both frost and light are currently unknown (I haven't decided where to put them yet)

Neat location choices

Thank you!
