That's a cool take on giants. NiceGiants are souls of mountains and other features of nature, that sometimes roam ethereally and manifest ghost-like.
The difference between an Elemental and a Giant is, the Elemental is animation of the physical matter, while the Giant is the manifestation of its soul, its spirit.
Most Giants are humansize Medium, but some individuals grow to whatever height corresponding to the natural feature.
Do you have a favorite bit of re-loring someone else did, fan or pro?
Aboleths? - as in your angels and genies are gigantic aberrant tentacled mindbending hagfish?This is probably seen more as replacing rather then re-loving, but one of the big changes I made was removing the genie species as the highly intelligent elemental powerhouses and replacing them with Elemental Aboleths, and changing the standard Angels, Planetars, and Solars of the divine heavens into Celestial Aboleths.
Wow...the dragon re-loring is exactly what I've done for years.I tend to "relore" to minimize the wide array of creatures available, while still making it possible/plausible for them to exist in the homebrewed world.
The most blatant is probably reloring basically all draconic creatures to being mutated or "unfinished/incorrect" offspring of actual dragons. It leads to the limited, and continually shrinking, numbers of actual full "wyrm" dragons. The most common varieties are the wyverns, hydrae, drakes (roughly worg to lion-sized wingless bestial dragons), and "lapdrakes" (my homebrew's "pseudo-dragons"). Linnorms, dracolisks, dragonnes, behirs, etc... are all dragon offspring that didn't "cook" right or completely, or were somehow tampered with (by magics) before hatching, to produce a "true" dragon. At least half of every dragon egg clutch, nowadays, is producing these "faux" dragon/draconic monsters. No one knows why. But the dragons, themselves, are becoming increasingly concerned with the future of their "true" species.
