TEXT: Ljosálfar (Light Elves)
  T
  he most striking features of the Ljosálfar are
  that they have pale blue/green eyes, pale white
  or green skin, and hair that can range from
  stark white to a deep forest green. There are
  other less common physical features present
  among their species, their skin can be bronze,
  golden or even platinum in some cases, with
  eyes that range from violet to golden. They have an unsettling
  gaze that is uncomfortable for people not accustomed to treat
  with the Ljosálfar. They are also very lithe compared to
  humans, with elegant features, long limbs and sharp ears.
  History
  Light elves, also known as the "Ljosálfar" (singular Ljosálf) ,
  are the opposite of the drow. Hailing from the Feywild,
  descended from a mix of primal elves and dryad, light elves
  are fierce rivals of the drow and see them as their tragic elven
  cousins. Light elves still retain some features from their
  dryad ancestors, and as such they feel more in touch with
  nature than with other sentient races. The first Ljosálfar, Elio
  the Light-Giver, born from unnamed parents deep in the
  Feywild, was also the first of their kind to leave the Feywild
  with a few other Ljosálfar and found peace within the deep
  fjords and green landscape of the southwest of Miklagard,
  later named the Alftindur Sierra. Here they founded over
  many decades what is now the Capital of Alfheim: Amvalora,
  a city that shines like a beacon at night and can be seen from
  miles away. The Ljosálfar have an indifferent relationship
  with the rest of the races. They commonly cause humans
  illnesses due to their isolation and different immune system,
  but they also have the power to heal them, and seem
  especially willing to do so if sacrifices are offered to them.
  Society
  Generally they live deep in lush forests with lots of vegetation,
  or high up on the tops of mountains. Their homes are
  normally made out of crystal, vines, and magical gems that
  they form over many years, reflecting light and making their
  towns almost blinding for outsiders. They abhor anything that
  goes against the natural way of things. Most light elves follow
  a set of beliefs and rules, a creed they call "The Path" that
  was created by Elio the Light-Giver.
  The Path
  Like an innate moral code, The Path is a series of beliefs and
  rules that the Ljosálfar are born with and uphold at any cost.
  The Paths core beliefs are:
  1. Darkness is simply the absence of light, so we must
  brighten the light until darkness is no more.
  2. Do not allow the light to die in your own heart, be the
  light when others cannot or will not be.
  3. The drow are the epitome of darkness, and must be
  destroyed without mercy to truly spread the light.

  Ljosálfar Traits
  Ability Score Increase. Your Charisma increases by 2, and
  your Dexterity score increases by 1.
  Age. Although Ljosálfar reach physical maturity at about
  the same age as humans, the elven understanding of
  Adulthood goes beyond physical growth to encompass
  worldly experience. A Ljosálf typically claims Adulthood
  around the age of 100 and can live to be 750 years old.
  Alignment. Ljosálfar are very lawful in nature, due to their
  innate moral code. Also a typical Light Elf is taught from a
  very young age what to do and what not. They tend to lean
  towards neutral, with some interpreting The Path differently
  or abandoning it completely and leaning towards good or evil
  respectively.
  Size. An average Ljosálfar stands at 5 - 6 feet tall and
  weighs around 120 pounds. Your size is Medium.
  Speed. Your base walking speed is 30 feet.
  Fey Ancestry.. You have advantage on saving throws
  against being charmed, and magic can’t put you to sleep.
  Be The Light. Ljosálfar are resistant to radiant damage.
  Partial Photosynthesis. Due to the Ljosálfar's affinity with
  the sun, each hour spent in direct sunlight counts as if they
  had consumed 1/2 pound of food. Also, when a Ljosálfar
  takes a short rest spent in direct sunlight and doing only light
  activity or meditating they can double their constitution
  modifier on any hit dice spent.
  Acute Vision. Light Elves have lost their darkvision due to
  many generations of living permanently in light, but they have
  gained better focus. You are proficient in Perception, and
  when you make a Wisdom (Perception) check in direct
  sunlight or bright light you make this check with advantage.
  Ljosálfar Magic. As a Light Elf, you know the light cantrip.
  Once you reach 3rd level, you can cast Faerie Fire once per
  long rest. Once you reach 5th level, you can also cast the
  Moonbeam spell once per long rest. Charisma is your
  spellcasting ability for these spells.
  Speak With Plants. You can communicate with plants as
  if you shared a language.
  Trance. 4 hours of meditation counts as a long rest.
