Harmony Gem

**Harmony Gems** are the power sources for chosen magic users (as everyone can use magic, but only Chosen Ones can become Guardians of Harmony) and are the source of their battle gear. Unlike *Madoka Magica*, they do *not* contain their owners' souls.

Darkness spreads into a Harmony Gem when a Guardian of Harmony experiences despair and similar negative emotions due to a bit of Chaos (also known as Zetsubo no Yami) residing inside everyone just like the Light of Hope (or Kibo no Hikari). Although it can usually be prevented with enough willpower or positive emotions, it is sometimes inevitable that a Harmony Gem (and Power Necklace) will be fully corrupted and transition into a Grief Seed. Once the affected Guardian transforms into a witch, they will need to be purified in order for them and their Grief Seed to be returned to their normal forms.

After the establishment of the Law of Cycles at the end of season 16 (the final season), the witch that forms from a Guardian of Harmony is prevented from forming in the first place, which causes Guardians who have lost the will to live to instead simply fade away, but they can be brought back to life like a witch can be purified.

## Grief Seed Transitions

### Season 1

* In "A Zany Date Scheme," Joy goes way too far while trying to set up a date for Victoria and Arcturus. Arcturus loses control and lashes out at everycreature, making him become a witch. This happens again in the next episode ("Joy's Goof-Off Day"), but *Victoria* is the one who loses it and witches out instead.
	+ This gave Joy a very important lesson in life...the hard way.

* In "My Greatest Regrets," Mira starts to doubt if she really deserves her Guardian of Harmony powers after she was created by and originally served Tenebrosum Leucosia. The others notice something is off about her behavior, but she refuses to tell what's wrong and cries when nocreature else is looking, resulting in her turning into a witch.
* In "Emilia: Untransformable," Princess Emilia is accidentally reminded of her mother and her home and becomes depressed, even refusing to eat. She expresses her extreme anger over her mother forcing her to leave against her will for (from her perspective) no reason and even cannot transform and participate in the battle as a result of this unresolved isssue, resulting in her witching out.

## Trivia

* Despite their appearance similarities, the Harmony Gem is *not* like the Soul Gem from PMMM. Kyubey does make a 4th-wall-breaking statement concerning them when she and Homura meet for the first time, however.
* Once they are created, they and the host's Power Necklace will be connected.
* While it may look like Katrina (since Event Horizon's identity is known to the audience from the start, but not the characters in-universe) fell into despair and became a witch, Event Horizon is *not* a witch. She is instead corrupted via normal brainwashing, which is also known to the audience from the start.
* When experiencing despair and similar negative emotions, the Power Necklace and Harmony Gem will glow dark purple.
* It has been confirmed that the Divinity will permanently remain alive as the real Law of Cycles, after much brainstorming by the main creator. Not only that, but all of the Guardians of Harmony in the past, present and future will be part of the Law of Cycles too.
	+ This is also confirmed in the final episode with Queen Estrella's line "The role of the legendary warriors is over for now. But when the world needs them again, future generations of Guardians will stand up against evil and despair," and Cynthia Moonpath's reply, "Yes, they will." The latter, rather than trying to fight the final witch of the series (Walpurgisnacht), later says to Kyubey "With a broken heart, the magic will Katrina-senpai made must end since ***I wish that the Divinity remains alive so that She can erase all witches from existence before they're even born. Every witch in the Multiverse, from the past and the future...with Her own hands!***" It is that wish that the Multiverse is completely reborn, with the laws of nature being altered and the life of every Guardian of Harmony becoming a semi-immortal thing.
* Harmony Gems come in three forms: the Gem form, the Jewelry form, and the Transformation form, the shape of which is unique to each individual Guardian and gem. As an error, however, the transformed form of the Gem is drawn like Madoka's Gem in some of the concept art for characters made by Foodyeater.
* In the gem's Jewelry form, each character's first name (or the first word of it, if pony) are written in runes. Twilight Twinkle (an exception), Sparkle Hope, and Twilight Sparkle really take the cake, as their name are respectfully written (in runes) as "Twinkle", "Sparkle", and "Twilight".
* Like Power Necklaces, if somebody is corrupted/brainwashed in their transformed state, the Harmony Gem will disappear and then reappear when the victim is returned to normal, as shown with Katrina. In her case, since she is technically in her Guardian form, it is implied that her Harmony Gem and Power Necklace, despite disappearing and not being visible, are still the main source of her powers but corrupted, though it is unclear how this works or where they go in this state.
* The Harmony Gem and Power Necklace do not work if their owner is having serious doubts about themselves. For duos, they do not work if their owners have a serious unresolved conflict between them.
* Since Harmony Gems do not contain their owners' souls, it is unknown why breaking it in their owner's transformed state, but not untransformed, (as shown in "The Truth About Homura"), often kills them.
* Harmony Gems are small enough to fit in their owner's palm/hoof. However, they are still very fragile in "egg" form and can potentially get broken easily, which is why they are kept inside rings/jewelry when not in use.
