[CHAMPION CONCEPT] Nerus, the Future of Zaun
LORE: Son of Ekko's son and Singed granddaughter (Ekko's grandson, Singed's great-grandson), comes from future Zaun. A planed invasion from the Void opened a gargantuan void-gate which produced time distortions imperceptible to most, but strong enough for time sensitive beings such as Zilean to become affected by them. Grown desperate with temporal echos of his long gone homeland, Zilean started redirecting magic power from the city to his intent of time shifting his Homeland to the future as his last chance to save it. Such redirection of magic power took a toll on Zaun's citizens with shortages of power, which generated civil unrest and set the bases for a crisis, which was enough to get the attention of a powerful denizen of the city, a mechanized Viktor devoid of most of his humanity, whom had seen use for the great amount of magical power gathered by Zilean, and organized an attack to Zilean's laboratory that lead to a massive cataclysm that shook Runaterra in the event knows as the Trinity Doom, combining civil unrest, the temporal cataclysm that engulfed the world, and the void invasion that started soon after A time jump so large would normally be impossible for most beings, Nerus knew this, even when being possibly the only one left with any kind of time-warping technology, having the luck of inheriting it from his proficient grandfather who could build time technology from scraps, though sadly deseased, but the time magic needed to power it behind the high temporal density "wall" of the cataclysm would be immense, even to send only one person.
Riding into one of the constant, but unpredictible "time quakes" that randomly shook Runaterra would be too dangerous as they were as unstable as they sound.
The only option to get behind the "time wall" of the cataclysm to reach his proficient in time magic grandfather when he was alive, to prevent these events, was to get in the place where the "most stable" time magic could be found: The (found) City of Urtistan His only hope to reach the city was a mad man that had his sanity long consumed by the void, Kassadin. When Nerus reached him, Kassadin didn't need an explanation, he just grabbed Nerus by the wrist and just like that, he sent them to a place that looked like a desert of void, with one thing that standed out, a spire that gleamed like gold. Kassadin extended his arm poiting at the spire and said - Urtistan. The unrest and aerie feeling only grew worse as they marched to the city, but it wasn't the gold spire or the multi-color nabuloses that they could now see at the base of the city, but something else, the feeling of prey being stalked from a bush.
While closing in the city, Kassadin shook and started levitating, and while Nerus was trying to aid him, he noted a dark hole expanding in Kassadin's chest, Kassadin made a gesture so Nerus would stop, he agonizingly pointed at Urtistan and said his final words- I can never escape the void. As the hole kept growing, Nerus saw void creatures inside, they somehow knew what he was up to, he though. And as Kassadin was already gone, he could only run to Urtistan. Almost in the city, Nerus noted that the void creatures slowed, but didn't stop, their pace, the golden gleam of the city was likely bring the cause.
Thud crash the city shook. A Void Leviathan, a void giant that has been devastating regions around Runaterra for it's capacity of bringing armies of void creatures inside it and mostly, for being able to take away the most effective weapon against them: a Void Leviathan was able to eat light. Nerus ran though the routes of the city, being unable to appreciate it's exotic charm, for light grew dimmer, void runner grew near and he came to realize he either didn't know how to tap in the time magic in the city, or said magic was not as powerful as he had expected.
Void creatures came to attack range and Nerus started shooting, he was now lost in the city, running where he found light, shooting, desperate, giving out on his plan. Was the city out of power or was he unable to tap it due to his ignorance? He should have expect more time with his grandfather learning, he should have known the void was watching him thru Kassadin, he should have been able to save Kassadin. But now, that were only his last regrets, he was in a golden hall, with a floating gem in the center emanating a golden aura. That didn't matter now, he didn't know what it was, how to use it, and it didn't emanate time magic, a fashionable candle could be much more in the eyes of a desperate man. Voidlings battered down the halls door, Nerus wasn't going to run more, there could be infinite darkness until the next light source, which he didn't know where it was, and didn't see a point of reaching.
He reached for a chair and started making his peace, still, he wasn't going down without making the burden of fighting the void lighter to those left. He was going to shoot down as many void monstrosities as he could before all light were dark. He shoot, they came, he shot, more came. As they advanced the wave of creatures avoided the gem, and as that happened, a lightning came of our it, consuming a voidling, that was as useful as throwing a glass of water at a fire. So then, the gem grew dark, now expanding black light. Nerus needed to stop this, he shoot the gem, the gem threw another lighting at his toxic shot, and Nerus put his gas mask on as they gem started to spread a noxius cloud. Enough to kill all small voidlings that entered the room. But he couldn't leave, and he couldt be there forever and larger void creatures could still enter end survive the room long enough to give him a fight. Exahusted and still fencing off monsters, he "plugged" his time device to the gem, started to program the device, and before he could do it the gem had turned to time magic.
After a flash, there was no void, there was no gem. There was calm crash, it all went dark Nerus woke up in the same, crashed and completely destroyed golden hall, dislocated from any city, a hall in the middle of nowhere, further behind the Time Wall that what he had intended....
Friends: 
Rivals: 
Role: Mage Even though he could look as a marksman, he is a mage, as his weapons are designed in a way they mostly "enhance" his abilities, instead of being a main source of damage.
Abilities: Q-
Corrosive Gun / Phase Charger Swaps between 2 set of weapons.
Corrosive Gun: Auto attacks use guns that deal (50% AD) attack damage, then leaves a stack of "Corrosion" on the enemy, dealing 5/8/11/14/17 (+ 17/19/21/23/25% AP) magic damage over time. Corrosion" stacks up to 2 times.
Phase Charger: Vents energetic excess energy and byproducts of his suit. Locks on an enemy for 2 seconds, the lock range increases with the time locked, then deals 10/16/22/28/34 (+150% AD) (+60% AP) true damage which decreases the target's magic resistance by 10/15/20/25/30 % for 1.2 seconds. Phase Charger weapon channel time is slightly reduced with BONUS attack speed and decreased more with cooldown reduction, up to a lower limit of 1.4 second. Phase Charge gains 30/60/120/150/180 base range.
Targets hit with Phase Charger get "Charge Affinity".
E- Necrorrosive Agent:
Throws a Necrorrosive Grenade to a target location. Nerus gets 5/10/10/20/25 armor and magic resist inside and enemies inside are slowed by 30%. If the enemies have "Corrosion" when the grenade explodes, they receive 80/110/130/150/180 (+90% AP) magic damage when the grenade explodes.
W-
Sends forward a small modified Timewinder damaging non-champion enemies in it's path. When it hits an enemy champion, deals 100/130/160/190/210 (+70% AP) magic damage to it and comes back. The winder follows champions with "Charge Affinity" and bounces to other enemies with Charge Affinity, leaving them in a 2 second stasis.
When the Mini-Winder hits an enemy champion, it leave a mark on the floor where Nerus and its target where, recasting this spell sends Nerus to its target original position and vice-versa. If multiple enemies have "Charge Affinity", the winder bounces too all of them, not leaving the mark but stunning them for 1.5 seconds instead. Nerus leaves another mark, when reactivated both champions swap positions
R-
If Phase Charger is active: Sends and controls a time Phantasm of himself, recast to teleport to it's location and gains a shield, a burst of movement speed and can cast 3 Phase Charger shoots with short delay, the longer the Phantasm is on, the greater the shield and movement speed, and the lower the cool down on his 3 Phase charger shoots.
If Corrosive Gun is active: Nerus dashed forwards and sprays Ultra Corrosion in a cone, adding 3 stacks of "Corrision" to every enemy and increasing the maximum amout of these stacks they can have to a total of 5. Enemies also have their resistances lowered by 15/30/45 % while they have any stacks of Corrosion for the duration of this spell.
Im obviously not an artist, but wanted to make the concept, had fun doing it though.
