Ashen Darke

Ashen Darke (Born June 20th, 1837) is a British butler and former member of the League of Shadows turned ally of Clark Wayne, who operates as the vigilante known as Batman.

The League of Shadows
Born sometime during the time of Queen Victoria, Ashen Darke was just a nameless orphan boy who found himself taken from the streets and used as practise for the League of Shadows recruits who were based in London.

The recruits were told to choose a child and then after that their mentor explained they were to kill the child. The girl who had chose him couldn't go through with it and dropped her blade and when she attempted to plead with her mentor he grabbed that blade and ran her through with it before attempting to take out the mentor. He took her place under this man and through him he learnt how to read, write and of course kill.

Eventually there came a time where he had to kill his mentor to succeed him and he did it without hesitation but with some mercy with a quick blade to the heart.

His defection from the league came in 2015, Ashen was sent alongside others to obtain the granddaughter of their current Ra's; Talia Al Ghul and they did with Ashen delivering the killing blow to the mother of this promised child and to his surprise he was told to train the child and he did so, he trained her as best he could but when she failed him he was given instructions to kill her and then use the pit to revive her as someone who would far more complacent.

Departing The League of Assassins
Unable to flee with the child, he instead abandoned the league when it was revealed his protegee had also been told to kill her mentor something that further disillusioned him. He survived the attack and faked his death, the believed death instilled the league and Ra's with hope for the child and she continued on her training.

When the first league of shadows members resurfaced in Gotham, Ashen originally believed they were there to finish the job and ditched his fake identity to dispatch of them, unwittingly crossing paths with the newer Batman who he offered to help given his years of experience with The League and fighting. Appearing publicly as the young vigilante's butler since then.
