Giants

Giants are a race of massive beings that, when fully grown, have been known to grow over 30,000 feet. Of course, their exact size is dependent on the giant's exact sub-species.

Biology
Giants, unlike dragons, have a maximum height of an excessively tall mountain and their offspring actually begin at the size of humans. A female giant can have a hundred children in one batch, dependent on their size. Giant children are actually a lot more vulnerable than most apex-predator offspring and thus Giants make up for it by caring for their young and having a great number of children to begin with. Giants can look like humans but they can also have glowing eyes or green skin and tendrils of vines forming off their skin, and some look like rocks or gigantic golems, and their diversity is so great that it would be more apt to describe giants as a genus, or perhaps even a family rather than a species, though giant children will always look like humans.

A giant is sentient from birth and at the intelligent level of an adult human from birth but as they grow so does their intelligence. Giants will have family units with two parents and many offspring, but once the offspring grow to sufficient size, about half their parents, they will leave the nest. A giant does not sustain themselves on the normal foods like berries or sheep, though they can, and instead have massive organs specifically built to store magic as an energy source and a nutrient source, though infant giants will still require to eat things like coal, something that naturally attracts magic.

Capabilities
Most giants are naturally adept at detection magic and naturally use it without thinking, enabling them to detect even ants easily. Most giants can also perform 'skin' magic naturally, as in they imbue their skin with something to defend themselves, whether that be electricity, stone, fire, or something else.

Inter-Species Relations
Giants and dragons have been known to get along, and even defend some human villages together against a greater threat, but generally giants and dragons will leave each other alone as a fight would severly wound the victor. There are, of course, exceptions that can lead to devastated valleys and massive skeletal structures from eons past. Giants will act benevolent to humans in general, perhaps due to the resemblance of humanity and a giant's children (it might've even been why humanity evolved their appearance, to benefit from this) and giants will also act kind to Satomi and most sentient races, though giants seem to like to be around Satomi and Humans in particular.
