Last time in my series on the fey, I looked at goblin markets and ways that DMs can present them in-game. This time, I’m going to an upper end of the fey power-scale. The goal of this series from the beginning was to populate some of the Challenge Ratings that don’t feature fey. How about CR 30, and the kinds of fey that might make the Archfey nervous?

Fey Chivalry | Fey Huntsmen and Leashed Terrors | Faerie Tales: Naiads, Pixies, and Sprites for 5e | A Visit to the Shadowfell – Shadar-Kai & More | In a Goblin Market | Fey of the Elder Starlight

Many stories involving elves and fey from more recent years (as opposed to fairy tales of antiquity) put their emphasis on mystical bindings and the superiority of the eldest things. Tolkien’s Ainur are greater in every regard than the Eldar, and the Eldar in turn have their own ranking linked the light of the Two Trees. With that in mind, as well as Zeus’s revolt against the Cronus and the Titans, I suggest that there were fey before even the Archfey. These Eldest of the fey ruled the Feywild before the burning brightness of the Sun came into being, when there was only twilight and full darkness (it’s the Feywild, maybe that could happen).

Immortal as the fey of the elder starlight were, their offspring and inferiors – the Archfey – could never come into rulership. Now the Archfey had been divided into Seelie and Unseelie, to war against one another in accordance with the whims of these eldest fey. Titania and the Queen of Air and Darkness had, therefore, only one thing in common: a desire to cast down the eldest and rule in their stead. They fought their rebellions separately, in parallel, for they could never trust one another. In the end, they sealed away those who had ruled in the elder starlight, and became the first of the Archfey that rule the Feywild today.

Yet the power of the elder starlight has not faded; in fact, the fey can still craft garments of it, or coalesce it into a dew. They gather it from the binding-gems and other relics that hold the eldest. Naturally, this means that in the late stages of a campaign, when cosmic threats are on the table, the fey of the elder starlight might slip their bindings. Any of the following might be a good reason:

  • One of the Queens is in such danger that she has no choice but to unleash the most awful power within her grasp.
  • A god of thieves steals a binding-jewel from the Queen of Air and Darkness, and the whole world gets more than the god bargained for.
  • The binding was limited to 10,001 years, and now comes to its end.
  • One of the fey of the elder starlight fled to a demiplane of masks and mirrors, where his last image could never be found and destroyed. The first sign of his return is the rending of the Starlit Loom, where his sister was imprisoned.
  • To free an imprisoned god at the end of a long quest, the heroes complete a mighty ritual that sunders many ancient bindings.

Elder Starlight. The Eldest are continually bathed in elder starlight, which harms non-Eldest creatures. When a creature comes within 5 feet of an Eldest for the first time in a turn, or when it starts its turn in that area, it must pass a DC 23 Constitution saving throw or suffer 4d10 radiant damage. On a successful saving throw, this damage is halved. The Eldest may prevent all damage to a creature from this effect if it wishes.

Masters of the Lesser Fey. Any creature of the fey type has disadvantage on all attacks against the Eldest, disadvantage on saving throws from effects created by the Eldest, and deals half damage with any damaging effect against one of the Eldest. This trait does not apply to elves or half-elves, despite their fey heritage.

Innate Spellcasting. The Eldest’s innate spellcasting ability is Charisma (spell save 23, +18 to hit with spell attacks). It can innately cast the following spells, requiring no material components:

  • At will: bestow curse, conjure fey, greater invisibility, faerie fire, dominate person, moonbeam (cast with a 5th-level spell slot)
  • 1/day each: foresight, dominate monster, etherealness, dimension door, mirage arcane

When the Eldest spends an action to cast a spell, it may make a single weapon attack as a bonus action.

Legendary Resistance (3/Day). If the Eldest fails a saving throw, it can choose to succeed instead.

Magic Weapons. The Eldest’s weapon attacks are magical.


  • Multiattack. The Eldest makes three longsword attacks.
  • Longsword. Melee Weapon Attack: +17 to hit, reach 10 ft., one target. Hit: 42 (8d8+6) slashing damage.
  • Starlight Blast. Ranged Spell Attack: +18 to hit, range 600 ft, up to three targets. Hit: 49 (9d10) radiant damage.

Legendary Actions

The Eldest can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The Eldest regains spent legendary actions at the start of its turn.

  • Attack. The Eldest makes one attack.
  • Adaptive Immunity. The Eldest becomes immune to one damage type dealt to it on the previous creature’s turn. This immunity lasts until the end of that creature’s next turn.
  • Rend Magic. The Eldest casts dispel magic without requiring material components.


Alternate Legendary Actions

Variant legendary actions are a great way to introduce variety, if your PCs are likely to face more than one fey of the elder starlight. (I feel kinda bad for your PCs already.) Creatures of this power level should feel like individuals, first and foremost. Attack should probably stay where it is, because it’s good reliable damage output. Adaptive immunity is there to make sure the whole party isn’t a one-trick pony. Rend magic is a way for the Eldest to shake off some kinds of conditions, without going down the road of condition immunity. Adaptive immunity and rend magic are both good candidates for variation. Here are a few ideas:

  • Twilight Soul. Use this legendary action only when standing in dim light. Heal 100 hit points. Once the Eldest uses this legendary action, it may not do so again until the end of its next turn.
  • Cloak of Night (Costs 3 Actions; recharge 6). Use this legendary action only when standing in total darkness. The Eldest fades out of existence until the start of its next turn. It may not be the target of any attacks or spells, and is not in the area of effect of any spells.
  • Mystic Mirror (Costs 2 Actions). Copy a spell that targeted the Eldest in the preceding turn, choosing a new target or targets. The spell does not require material components, but the Eldest may not copy spells with expensive material components that are consumed in casting.



I don’t know for sure if the stats are “balanced” for a CR 30 creature. They come reasonably close, though the AC, attack bonuses, and non-hit-point defenses are higher than the book suggests. (The same is true of other high-CR creatures, like the empyrean.) In general I would say not to worry too much about the minutiae of balance in a creature designed to be one of the most terrifying things in your setting. Instead, focus on giving the fey of the elder starlight individual personality and goals, and following those goals to the point of beating the snot out of these puny mortals.

Masters of the lesser fey is there just to support the story that the Eldest are a threat to all fey, even (especially) the Archfey, without having to worry specifically about the CR of the Archfey, which might or might not be greater than that of the Eldest (because in most campaigns, PCs won’t fight the Archfey in person). Conjure fey is not an effective way to fight the Eldest, which seems story-appropriate to me. I did not, however, want to screw over elf and half-elf PCs with this; for your own campaigns, feel free to change that line and crush the elves beneath your perfectly-attired heel.

What I like most about the fey of the elder starlight is that they pose a new threat for the highest-level PCs, and put the PCs in a situation where even the Archfey come to them seeking aid. This should feel like a great reversal of fortune after 19 or 20 levels of dealing with fey hauteur. I hope you’ll find a chance to use them, or to make them part of your setting’s mythology just in case your PCs need a reminder that there’s always something bigger out there.
