Fairies do not possess souls. As such, when they die, it is permanent. There is no resurrection for a fairy.

"Before the sun sets on the third day, you've got to get dear ol' princey to fall in love with you. That is, he's got to kiss you. Not just any kiss - the kiss of true love."
—Ursula, The Little Mermaid

If a fairy falls in love with a mortal, the mortal must kiss the fairy by sunset on the third day or the fairy fades away into the wind, ceasing to exist. The kiss cannot be just any kiss - it must be "True Love's Kiss." Upon receiving this kiss, the fairy ceases to be a fairy and becomes a mortal just like their beloved - losing all their powers in the process. The reason for this is, true love's kiss grants the fairy a piece of the mortal's soul, allowing them to live a normal life and experience an afterlife, which they cannot if they are soulless.

Some say fairies only live for a season. Others say fairies can live about 600 years. Therefore, a fairy can live as long as you want it to... however long you believe.

In their natural form, fairies average between 5 to 6 inches in height and have a slender build. Your size is Tiny. The Tiny Players 5e Variant Rules apply to you.

Your base walking speed is 15 feet. You have a base flying speed of 50 feet and can hover, much like a hummingbird.

Your Strength score decreases by 2. (After all, you are a wee tiny being!) Your Charisma score increases by 2 and either your Dexterity or Wisdom increase by 1.

You gain proficiency in the Nature skill.

You can cast dancing lights, and minor illusion at will.

Once per long rest you can cast faerie fire without using up a spell slot.

You have advantage on saving throws against being charmed, and magic cannot put you to sleep.

As an action, you can transform your appearance to appear as a tiny sparkle of light (small enough to fit through a keyhole) or revert to your natural form. While tiny, you have advantage on Dexterity Stealth checks you make to avoid detection.

Once per every two days for one hour you can magically transform to large fairy form (medium human size or small size) retaining your wings and fairy appearance. You gain a +2 bonus to Charisma while in your larger form.

At level 5, once per day, you gain the ability to magically create a fairy ring (a ring of magical mushrooms). The ring has the properties of the magic circle spell.

At level 13, once per day, you can use your fairy ring to Teleport any who wander into it. If the ring is intended for teleportation, the destination is fixed and the ring lasts for 1d6 minutes. 

At level 18 you gain the ability to grant a single wish. Upon granting this wish, you will die and cannot be resurrected as you do not possess a soul.
