Damian Thomas Al Ghul and Dahlia Marinette Al Ghul, heirs to the Demons Head of the League of Shadows and the twin children of Talia Al Ghul and unbeknownst to them Bruce Wayne as well. When the two are separated as children, Dahlia unable to be found is pronounced dead within the League and is never spoken of again as to not anger the last heir. Dahlia separated from her twin, who she believes to be dead, is found by the remnants of the Order of the Guardians. What happens when Dahlia's name accidentally slips from Damian's mouth in front of his father and brothers? What happens when Damian's name slips from Dahlia's in front of her Parisian friends? What happens when these two long lost siblings are finally reunited at last? ~~~ Oki doki guys so lately I've been reading many mlb crossovers and this was inspired by Bio Dad Bruce Wayne aus along with a couple of Daminette twin/sibling stories I've found (which aren't many) and I decided to try out my own.
