- Due to lore reasons the Eladrin in this setting can't swap between the different seasons after a long rest like they can according to their entry in Mordenkainen's Tome of Foes. You pick your season on character creation and can't swap unless there is a good ingame/lore reason.
- The void Eladrin is the Shadar-Kai subrace.
Normal elves who have undergone the Eladrin Ritual, an ancient ritual invoked by the Elves only in the most dire of times to empower a group of champions to restore their land to its rightful harmony. The ritual always creates 5 Eladrin, one for each of the seasons and a hidden Void Eladrin. The ritual has only been performed twice in living memory, both to stop Areth. The first time during Areth's first invasion of Phantom World, resulting in catastrophe not at the hands of Areth but at the hands of the power hungry Void Eladrin Ilalokthramek. The second ritual was invoked by the Wood Elves on Hadira in response to Nightfall and while the Summer Eladrin Galaduil ended up working with Areth their plans were stopped by The Travelers amongst which were the Spring Eladrin Myra and the Winter Eladrin Maevin.
