Abilities
Lore: After the appearance of Xerath, many Hextech scientists wondered if such power could be duplicated or even imitated through a machine. Various experiments showed that conventional machines could not handle the amount of raw mana comparable to Xerath's. That was not the only problem. The scientists were only able to mimic similar magical force by requesting the College of Techmaturgy to allow them to redirect all magic energy used by the school into the core of the experimental machines. The scientists of the college could not find a suitable metal to cast the core and body from. Left with no other choice, the scientists were forced to ask for the help of Jayce. The requested that he somehow manage to chip away a piece of Xerath's sarcophagus. Nearly costing him his life, he was able to defeat Xerath in the Fields of Justice, and he claimed a small shard of his sarcophagus as his prize. With this they finally had a metal which could store a nearly infinite amount of mana. This they named the Xeracore, in honor of the being that inspired it, and the fact that this was once a part of Xerath. With the dilemma of core out of the way, now it was necessary for a metal that would serve as the body. After exhausting the college's funds, and their own personal money, the scientists obtained a ton of the precious Manametal used to craft Lucian's weapons. The metal's properties allowed it to be adapted by magic; it could be made harder of more malleable relative to the magic being used. With this, a miracle of science was created. It was far more advanced, yet much more simple, than anything that could have been created by Hextech, so it was not labeled a Hextech machine. Instead, they bestowed the title of "The Manametal Ascendant". The scientists bestowed a low intelligence in it so it may be easily controlled. Many scientists agreed that it should be used as a guard, and hence it was given its proper name, Sentrus. None dared to raid the college, not even Viktor, due to its immense power. However, one of the scientists believed that this miracle was the secret for spreading techmaturgy through Runeterra, through war if necessary. To prove his point, the scientist manipulated the machine's simple brain in order to cause it to go on a rampage. Through the efforts of Jayce, Vi, Ziggs and Caitlyn the machine was subdued, although much of the college was left in shambles. The League took notice of this incident, and realized that such a being would upset the balance of power between its member nations, and as such it was placed into the custody of the League to be used in battles in the Field. However, many summoners have noticed Sentrus is difficult to control whenever Xerath is in the vicinity, often fluctuating energy without warning.
