This is based on the above Idea
Forn The Eternal Prisoner
Melee/Tank
Forn is a creature formed from the fragments of all the souls lost during the last Harrowing in the attack on Bilgewater
It has no one conscience, changing it's voice and personality constantly between different people (man, woman and child)
It constantly seeks a way to become whole by absorbing more fragments of souls
Passive:
Incomplete Soul : Forn tries to find himself by copying real souls
Forns basic attacks let him copy 20% of the targets highest stat
He can attack another enemy to change the copy
- Hp not included
Duration : infinite (but grows as the enemy grows)
Cooldown : 40 seconds
Q:
Mimicry : Forn throws its ethereal chains at an enemy trying to take it's soul
If it's a minion or monster it deals damage
If it's a champion it roots himself and the target for 1.5 seconds and deals damage
After the channel it copies the targets Q for 5 uses (damage and cooldown also copied)
Cooldown : 15 / 13 / 10 / 9 / 8
Radius : 700
Damage : Magic 60 / 100 / 140 / 180 / 220 (+ 30% AP/AD) (+ 15 per 15 fragments)
*Can cancel early for just the damage and can be interrupted by any form of damage
W:
Ghostly Scream : Forn screams in agony with the Voices of a thousand lost souls
It screams in an aoe area around it, dealing damage and fearing anyone or anything caught in it
Cooldown : 25 / 22 / 19 / 17 / 15
Damage : 40 / 60 / 80 / 100 / 120 (+ 10% AP)
Radius : 300 (+ 1 
per 500 HP)
Fear Duration : 0.3 sec (+0.1 per 15 fragments)
E:
Life Sense : Forn feels and can faintly see any soul within a living being
Every couple of seconds its radar shows the position of anything living in an area with a small soul in the location (think rek'sai tremor but with souls instead of steps)
Cooldown : 10 / 9 / 8 / 7 / 5
Radius : 2000 (+ 1 per 10 fragments)
Duration : 0.2 sec (+0.1 per 12 fragments)
R:
Passive :
Soul Mutation : Forn is constantly trying to complete itself, absorbing all life he can find
Forn absorbs fragments of souls dropped by champions (allies included)
Increasing the effectiveness of his abilities
*roots itself for 0.1 sec to absorb
Active :
Perfect Bound : Forn forces all his fragments to form a single perfect soul for a couple of seconds, giving him Immense power
Forn gains bonus MS, MR, Armor, HP and increased range for the duration
Cooldown : 120 / 100 / 80
Movement Speed : + 20% (+ 2% per 20 fragments)
Magic Resist / Armor : 20 (+ 1 per 15 fragments)
Health : 200 (+ 50 per 15 fragments)
Range : 500 (+ 1 per 30 fragments)
- still considered melee
Fear Duration : 0.5 sec (+0.1 per 20 fragments)
I think of him as a manaless top laner, made to NOT have a defined role, his passive and Q serve for him to both thematically and strategically fight in equal ground to most enemies
His W serves for both engages and running away, plus he can interrupt channels with it
His E is most of all for thematic reason but also works well to serve as a constant semi ward that both can keep him safe and help chase down enemies in the jungle
His R serves to change his play style come level 6 and to give him a good engage and teamfight power, since apart from his W he doesn't really have any aoe abilities
When he hits level 6 his purpose changes to gather as much fragments as possible, but since they only drop from big things it makes him want to teamfight and roam more, instead of farming in lane
