Nyarla The Mother of Dark
Role: Mage / Assassin
LORE Within a Small Colony in the Shadow Isles, there once lived a beautiful woman. One of her dreams was to start a family, something that she would not be able to live without after what happened to her in the past. Sometime before the Ruined King fell, the woman was impregnated. All she had hoped for had come true...
...or so she had thought.
The Hidden Colony within the Shadow Isles was outcasted for its practice of murder, in hopes to please their dark deity. The tradition of sacrifice is what makes up the colony. But they do not sacrifice any normal human, instead they choose a random Newborn Child to kill in order to protect themselves from "the malice of the dark god". The unfortunate child whom was to be sacrificed that year was the woman's firstborn son, Filius. The Colony forced the poor woman to take her baby's life with the tip of a dagger.
Traumatized and heartbroken, the woman fled from the Colony after the terrible deed, never to be heard from again. Several Years later, the Ruined King fell. The Shadow Isles was overshadowed by anarchy. Many years later, reports confirmed that what seemed to be a Hidden Colony was completely destroyed. Corpses painted the ground of the hamlet. The reporters also said they saw what appeared to be a mysterious black figure in the distance, and they could also hear what sounded like a song from a Child's music box. A few seconds later, they received a chilling message from the figure, in a haunting and distorted voice.
"They've met with a terrible fate, haven't they...? Hee hee hee.........."

KIT
Passive "The Grim Rune"
- When Nyarla comes within range of an enemy champion, that champion is marked with The Grim Rune for 10 seconds.
- During this time, Nyarla deals 2% (+1% per Champion Level) {3% at L1, 20% at L18} more damage to the victim.
- Upon killing a target with the Grim Rune active, Nyarla is healed for 20% of her missing Health.
- If multiple enemies appear at once, the Enemy Champion with the LOWEST Armor and Magic Resist is marked with the Grim Rune.
- The Mark is lost when either Nyarla dies, the Victim is murdered, or if the victim manages to escape Nyarla's sight range. If the mark is lost, the passive goes on cooldown.
- This passive has a 20 Second Cooldown in between markings.
Q Ability "Sunder"
- Upon activation, Nyarla blinks towards a Target Enemy within a medium-range distance, and deals 90/120/160/210/250 (+70% AP and 2/3/4/5/6% of the victim's Current Health) Magical Damage to the victim.
- If Haunting Lullaby (W1) is active, then the attack will inflict an additional 5/10/15/20/25% Magic Resist and Armor reduction curse for 4 seconds.
- If Song for Filius (W2) is active, then the attack will inflict a 10/20/30/40/50% Slow for 2 seconds.
- If Haunting Lullaby (W1) is playing, and Nyarla activates Stalker's Hex (E), within several seconds, the attack will additionally inflict the Fear status for 2 seconds alongside the MR and AR debuff.
- If Song for Filius (W2) is playing, and Nyarla activates Stalker's Hex (E), within several seconds, the attack will Root the victim for 2 seconds instead of slowing them. COOLDOWN: 7 seconds MANA COST: 70/75/80/85/90 Mana TYPE: Target Enemy RANGE: 400
W Ability "Haunting Lullaby / Song for Filius"

- Song for Filius passively boosts her Movement Speed and Attack Speed by 10/12/15/18/21% while playing.

- AESTHETIC: When playing Haunting Lullaby, Nyarla hums a very, VERY distorted tune that will send haunting chills down someone's spine.
- AESTHETIC: When playing Song for Filius, Nyarla plays a slow-paced song from a Child's Music Box.
- All Players will be able to hear these tunes, but only if Nyarla can be seen by them. COOLDOWN: 3/2.5/2/1.5/1 seconds MANA COST: 0 Mana TYPE: Passive (Switchable)

I have no real ideas of what Item Sets she would have, but this is an interesting concept I came up with. Post your thoughts below! I hope to make the creepiest Champ since Satan himself!
