Jade artefacts, armour in particular needn't be plain objects but could resemble creatures that live in the region of Creation where it's Elemental Pole is. I thought of the idea from the cover of The Sea Watch. The man's armour looked like a crab beastman. I thought why make jade as plain as just being elemental which makes it rather dull. Wavecleaver Daiklaves made from water jade that's turquoise and looks like shallow blue water are cool, but basing artefacts on living things would make them so much more interesting. This would go with ideas about making Lunars more orientated towards the Wyld rather than just animals, although Terrestrial Exalted wouldn't have the power to transform themselves, although they could call on an animal's characteristics. For example a crablike suit of water jade power armour would give them great strength and protection.
   Terrestrial Martial Arts also seemed very dull. I think they should be solid rather than boring. For instance they could include animal styles, or at least versions of animal styles but replicating the immediate traits of an animal such as reproducing it's movements. My version of Snake Style with fighting chains to mimic and snake's coils and tiger claws to mimic it's bite would be a good example. Celestial Styles are something deeper. Something about actually becoming like the subject of the style, not just physically but inside. It's not just about changing their bodies but their minds and Essences. In Sidereal Martial Arts instead of trying to change themselves into something, they try to absorb something into themselves.
