Ombrask

Those who wander the Shadow Plane are doomed to twisted fates and mired minds . These fading, lost souls begin to manifest monstrous forms, although some especially resilient individuals manage to pull themselves from this dark path before their essence is wiped clean. Known as ombrasks (OM-brask), these translucent creatures hail from a variety of heritages; from elf to dwarf, dragonborn to lotol, and rakin to goblin . All struggle to recall even the simplest memory, such as their former name, and all have a ghostly, colourless appearance .
One of the first things an ombrask forgets is its voice . Though it knows and can understand the meaning of words, its cadence, pitch, and patterns of speech fade from lack of use; the dreary, joyless experience of the Shadow Plane leaves little to talk about . However, ombrasks become especially sensitive to the psychic burst of emotion that accompanies death, the freeing of a soul from its shadow-numbed body . Ombrasks can latch onto the shreds of this psyche and adopt its speech patterns, learning to mimic them perfectly .
Next lost is the ability to feel, love, and smile; any emotion associated with joy or excitement is nullified. With prolonged distance from the Shadow Plane, or exposure to realms of strong emotion, such as the Plane of Fey or Springarden, these sensations can make a slow return for a lucky few . What is never lost is the memory of mundane tasks, such as ploughing, chopping wood, or polishing armour . Muscle memory is scarred into the minds of ombrasks, making them particularly deft at tiny, detailed work .
If an ombrask doesn’t find a way to exit the Shadow Plane or isn’t summoned by some novice wizard, it can fade entirely, becoming an invisible, skulking creature bent only on survival . In fact, there is strong evidence to suggest that the creature summoned by the unseen servant spell is one of these invisible creatures, temporarily pulled from the Shadow Plane . The fate of those too far gone is enough to stop most explorers from staying long in that dull and lifeless expanse .
A sense of adventure, a magical mishap, or a cruel curse, there are a multitude of reasons why a native of the Material Plane might find itself shunned to the Shadow Plane . Discovering who they used to be is a motivator for many ombrasks . Do they have parents? Cultural traditions? What is their history? On the other hand, some ombrasks, perhaps those with a foreboding sense of their past misdeeds, choose to ignore what might have come before and focus on living life anew . That is, if their previous life doesn’t come calling.

Voice Thief. While an ombrask can potentially understand any number of languages, it is a naturally mute creature . When a creature that can speak dies within 30 feet of you, you can use your reaction to absorb a piece of its psyche. After you have used this reaction, you can’t do so again until you finish a long rest. After you have absorbed a psyche, you can perfectly mimic the creature’s voice, cadence, and speech patterns indefinitely. You can hold a number of pieces of psyche (and mimic a number of voices) equal to your proficiency bonus. If absorbing a new piece of psyche would put you over this limit, you must choose one psyche to be replaced .
