From what I’ve read, evil-aligned celestials are an extreme rarity, but evil-aligned deities exist. I’ve even heard that if a celestial turns evil, they stop being a celestial. Celestials supposedly serve deities, but it’s never been specified what type of deity they serve as far as I know.

  • Do celestials serve evil deities?
  • Do evil celestials actually exist?
  • Are celestials that serve evil deities also evil?
  • Can celestials be forced to serve an evil deity regardless of their alignment?

    \$\begingroup\$ Are you looking for just 5e content, or is previous edition lore something you want? If so, would be good to add the lore tag. \$\endgroup\$ – NautArch Sep 24 '19 at 13:52
  • \$\begingroup\$ In DND 4e they definitely could serve evil deities, though that may have changed during the transition to 5e. \$\endgroup\$ – nick012000 Sep 27 '19 at 8:19

It is possible for celestials, even the most powerful ones, to be tricked by evil deities. They might become pawns, initially unaware that they are being played with. They might eventually get corrupted and fall. A famous example is Malkizid, a solar who was seduced into betraying Corellon by Lolth, and was later cast into the Nine Hells. Another example (from 3.5e) of a celestial actively serving an evil power was Thah Rhalar, a hound archon minion of Set.

If you want some inspiration about how to modify celestials to serve evil deities, you might have a look at the description of angels serving the God-Pharaoh, who is actually the malevolent dragon Planeswalker Nicol Bolas, in the Plane Shift: Amonkhet write-up available as a free pdf from WotC. While not legal in Organized Play events, it is still some kind of "official" D&D-5e-compatible material.

    \$\begingroup\$ @MageintheBarrel Looks like a separate (and worthy) question. \$\endgroup\$ – KorvinStarmast Sep 24 '19 at 12:18
  • \$\begingroup\$ Love the lore, but are there similar examples in 5e monsters? \$\endgroup\$ – NautArch Sep 24 '19 at 13:22

    \$\begingroup\$ @MageintheBarrel: If you ask your question in a separate post as KorvinStarmast has suggested, we can answer that too. 5e MM has relevant information under the discussion of Angels. \$\endgroup\$ – ZwiQ Sep 25 '19 at 6:38

    \$\begingroup\$ @SeraphsWrath: The examples in that related question are surely relevant, but do not really fit this question's title: they are corrupted celestials but are not serving evil deities. Yet, they are definitely relevant, thanks. \$\endgroup\$ – ZwiQ Oct 18 '19 at 17:20

Zariel (Mordenkainen's Tome of Foes, page 180) was a celestial (solar), but she now serves Asmodeus as the Archduchess of Avernus. However, her fall seems to have turned her in to a Lawful Evil Archdevil. I don't know whether she could have stayed a celestial, or whether she could have kept a Good alignment.


Good aligned outsiders, per the Monster Manual, are Celestials. Evil aligned outsiders are Fiends. The Subtypes differ for each, so making a subtype of another kind would work. An Outsider (Eladrin, Demon) would have the evil alignment but the Eladrin and Demon subtypes. It works within the rules. An evil deity can still do good deeds, but usually for evil purposes. A Celestial would promote the good deeds, but not the evil end, and could unwittingly be used.

    \$\begingroup\$ Can you cite where in the MM it talks about this? \$\endgroup\$ – NautArch Sep 24 '19 at 2:04

    \$\begingroup\$ @NautArch I think that alignment of fiends is explicitly spelled out in the PHB, but I'll have to check later. I think this rules text addresses a part of your comment: Alignment is an essential part of the nature of celestials and fiends. A devil does not choose to be lawful evil, and it doesn’t tend toward lawful evil, but rather it is lawful evil in its essence. If it somehow ceased to be lawful evil, it would cease to be a devil (Basic Rules p. 36, but there is probably more detailed text in the MM for both celestials and fiends). Amaranthine; a supporting cite from the MM would help) \$\endgroup\$ – KorvinStarmast Sep 24 '19 at 12:19
  • \$\begingroup\$ The closest I can get without the actual book is in the first section of the MM before you get to any monster listings. If I recall, there is also a “sidebar” that tells you how to adjust monster types. I might be able to lay my hands on the book in the next couple days. \$\endgroup\$ – Amaranthine Sep 25 '19 at 4:18
  • \$\begingroup\$ I'm not sure they're looking to adjust, but for actual lore guidance. \$\endgroup\$ – NautArch Sep 25 '19 at 13:42
