Mordenkainen Presents: Monsters of the Multiverse
“To be not just ruled by emotions, but physically changed by them? Perhaps better to have no emotions at all.”
— Mordenkainen
Eladrin are elves of the Feywild, a realm of perilous beauty and boundless magic. Having adopted the Feywild as their home, and after centuries of exposure to the plane's ambient magic, the Eladrin have aquired supernatural abilities not seen in most of their kin from the Prime Material plane. Using that magic, eladrin can step from one place to another in the blink of an eye, and each eladrin resonates with emotions captured in the Feywild in the form of seasons — affinities that affect the eladrin’s mood and appearance. An eladrin’s season can change as swiftly and easily as one's mood, though some remain in one season forever. Choose your season or roll on the Eladrin Seasons table. Your Trance trait lets you change your season.
Eladrin Seasons
| d4 | Season |
| 1 | Autumn: peace and goodwill, when summer's harvest is shared with all |
| 2 | Winter: contemplation and dolor, when the vibrant energy of the world slumbers |
| 3 | Spring: cheerfulness and celebration, marked by merriment and hope as winter's sorrow passes |
| 4 | Summer: boldness and aggression, a time of unfettered energy and calls to action |
The eladrin were originally elves who found refuge in the Feywild when they were cast out from Arvandor by Corellon after his confrontation with Lolth. Unlike other elves, who then decided to move on to the Material plane, the eladrin chose to remain in the Feywild and adopt it as their home. Centuries of exposure to the wild magic of the Feywild changed those elves, imbuing them with the flexible and mutable nature of the plane, turning them into eladrin. While some eladrin managed to remain humanoids despite these transformations and only acquired some additional supernatural abilities, most were completely altered by the plane, changing into fey creatures.
Unlike other elves, eladrin did not feel a pressing need to return to Arvandor. Instead, they found themselves more strongly connected with the Feywild. There, their cities displayed extraordinary feats of elven architecture, blending magic, nature, and structures into awe-inspiring landscapes, some of which were designed to exist in and out of the Feywild, traveling between planes along with their inhabitants. The culture of eladrin civilization was older than any other elven culture in the multiverse.
Some eladrin believed that, if they led a life of upholding the ideals of the Feywild, they could reincarnate as members of the Seelie or Unseelie Courts, or even as archfey. Examples of eladrin archfey are the Prince of Hearts of the Gloaming Fey, or the Sea Lords Elias and Siobhan Alastai, the twin rulers of the Court of Coral.
Eladrin are similar to High Elves but are considerably more slender. It is common for their eyes to shine, giving away their connection to the magic of the Feywild. Their hair and skin colors change to reflect their moods, which can each be identified to a particular season of the year. How frequently eladrin change their appearance was an individual choice. Some eladrin spend their entire lives in the same season or follow the seasons of the place where they live, while others might change as frequently as once per day or more.
Note: When finishing a long rest, any eladrin can change their season. An eladrin might choose the season that is present in the world or perhaps the season that most closely matches the eladrin's current emotional state. For example, an eladrin might shift to autumn if filled with contentment, another eladrin could change to winter if plunged into sorrow, still another might be bursting with joy and become an eladrin of spring, and fury might cause an eladrin to change to summer.
The following tables offer personality suggestions for eladrin of each season. You can roll on the tables or use them as inspiration for characteristics of your own.
