As I gear up to finally finish this thing, a little post of my art of Lucy's zodiac spirits that appear in it. I won't be giving details now, but figured everyone would enjoy seeing them appear.

Celestial Spirits in order of height
this is not canon, just my reworking

Summoning Aquarius is the most costly in more ways than one. Also, Wednesday is literally called "water weekday" in Japanese.

If your still open to heacanons, do you have any headcanon about the celestial spirits? If you don’t that’s fine, thank you in advance if you do.
What headcanons don't i have lmao
Loke is the leader of the 12 Gates because he was the first one of them to be formed (irl the leo constellation is one of the earliest recognized constellations).
The Spirit King is technically the last of all the celestial spirits to be born. Though he has dominion over all the stars, he didn't gain a form until after all the 12 Zodiacs gained a physical form as he is the amalgamation of their powers and draws energy from them.
What we see of the zodiac spirits isn't their true form (you expect me to believe Loke was a catboy in a suit all these years? Or that Cancer was always wearing slick black pants with a popped collar shirt? Please) All of them have the ability to change their appearance based on how they desire.
Their true form however is how they looked upon initially being formed (for eg. Scorpio being a giant Scorpion, Ares a Ram, and so on) and is when they're at their most powerful with their magic completely unlocked and unrestrained.
Also they're all essentially genderless regardless of how they present (all a bunch of he/theys, she/theys and they/thems. )
Spirits can't exist outside of their realm, prolonged time on earthland will kill them. Which is why the keys were created in the first place. Being bound to a wizard's magic allows for them to take form on earthland without any repercussions in exchange for their services in battle. It also allows them to self summon. (An unbound spirit would dematerialize in a few days to weeks. Loke was an outlier tbh)
Zodiac contracts exist mostly to protect the wizard. Novice wizards can't handle a spirit at full (or even half) power and since they are linked could drain a beginner wizard with just opening their gates alone. Setting the terms such as specific days and how many times a month to be summoned serves to limit any dangers of magical exhaustion on the wizards part. As the wizard gets stronger these terms are reworked so they can be summoned more frequently.
Also as the wizard gets stronger they can get to use more of the spirit's abilities( I would like to believe that Virgo can do more than dig holes, Scorpio can do more just Sand Buster and Ares wool can do more than make peeps sleepy). You know like how in pokemon the better the trainer they can get access to stronger pokemon? Something like that.
If a key contracted to a wizard is lost it'll teleport back to them over some time, just not instantly. The greater the distance the longer it takes to teleport back to them.
There's an alternate way to summon the Spirit King apart from breaking a key. If all 12 spirits are summoned at once he can be brought forth through their combined power.
Certain constellations are visible based on the season, the spirits get a slight power boost if summoned in their respective season (like gemini and taurus is winter, Virgo, Leo and Cancer in Spring for eg.).
Their powers can be 'eclipsed' in 2 different ways. A lunar eclipse weakens theirs powers while a solar eclipse overpowers them and makes them go out of control for the time.
Please give me these two becoming friends over their shared thirst for Lucy and protecting her at all costs!!!
