Cosmic Elf (5e Subrace)
From D&D Wiki
Cosmic elves are very ancient and mysterious, having eldritch-influenced origins forgotten from generations of lost history. As appearances go, they do not look much different than most normal elves, aside from being much taller and slimmer than most. However, a few key differences do emerge with close inspection, such as their smoother, paler skin of varying faint hues. Their hair is short and of a black and silver color, and their eyes are black with silvery pupils. They quietly radiate strange energies, a weave signature that seems to shift between arcane, divine, and innate magics all at once.
