Description
After the War that broke the world a group of humans, too afraid to return to the surface due to immense losses, decided to stay underground. Over time, the intense magic of the Underdark sped up their mutation, giving them new magical capabilities while rendering their eyes useless. Their skin became gray due to the lack of sunlight. These mutated humans became known as the Tenebra.
Origins
The Tenebra were not created by any of the Fragments. Instead, they evolved from a group of humans who chose to remain in the Underdark after the war ended. This decision was driven by fear and loss, with the intense magical energies below accelerating their transformation.
Genetics
The Tenebra developed unique magical abilities as a result of their mutation. They lost their need for eyes, relying instead on heightened senses such as hearing and touch. Their skin turned gray due to prolonged absence from sunlight. Tenebra individuals vary widely in alignment.
Lifespan
Tenebra live up to 200 years.
Homeland
Initially hidden beneath the lands of Caldar, the Tenebra eventually found more suitable underground caverns below the sea between Caldar and Eratus, in the Desconocido. They maintained proximity to shorelines for easier communication with the surface and emergency exits in case of disasters.
Also Found In
Their underground territories extend primarily beneath the sea between Caldar and Eratus.
Reputation
The Tenebra maintained contact with surface dwellers for supplies in their early years, but eventually became largely forgotten by many surface civilizations. They kept the most contact with the Tritons, who lived at or visited the ocean depths.
Alive/Extinct
Tenebra exist and continue to thrive in the hidden depths of the Desconocido, adapting to their unique environment while maintaining some ties to the surface world.
Tenebra Traits
As a Tenebra, you have the following racial traits.
Ability Score Increase: Your Constitution score increases by 1, and you gain proficiency in a saving throw of your choice.
Type: Tenebra are humanoid.
Size: Tenebra are about the same size and build as humans. Your size is Medium.
Speed: Your base walking speed is 30 feet.
Dweller from Below: Tenebra having no eyes, have substantially different senses from surface dwellers. You have echolocation (blindsight) out to a range of 30 feet, by emitting low frequency soundwaves by simply breathing. You are blind beyond this range. Furthermore, you have tremorsense up to 60 feet, as you are extremely sensitive to ground vibrations.
Blind Adaptation: Without eyes, your other senses have been honed to unusual heights. You have advantage on Wisdom (Perception) checks that rely on hearing or smell. You are immune to effects that require you to see the origin (such as Petrifying Gaze). You cannot benefit from Devil Sight or vision through another creature's senses, as your brain's structure has changed and cannot handle images in that way.
Deep Echo: As a bonus action, you can emit a loud sound wave that grants you blindsight out to 60 feet until the end of your next turn. You can use this trait a number of times equal to your Constitution modifier (minimum of once). You regain all expended uses after a long rest.
Sonic Screech: As an action, you can release a concentrated sonic boom in a 10-foot radius centered on yourself. Each creature in the area must make a Constitution saving throw (DC 8 + your proficiency bonus + your Constitution modifier) or take thunder damage equal to twice your level and become Dazed until the end of its next turn (on a success, it takes half the damage and is not Dazed). You can use this trait once per long rest.
Subterranean Magic: You know the Thunder Note or Desconocido cantrip (choose at character creation). When you reach 3rd level, you can cast the Desconocido spell once per day. When you reach 5th level, you can cast the Detect Thoughts spell once per day. The ability score you chose (INT, WIS or CHA) is your spellcasting ability for these spells when you cast them with this trait (choose when you select this race).
Languages: You can speak, read, and write Common and one Standard language of your choice.
