Please be informed that Arlecchino is not in very many comics I have found. If the casted VA is willing, I can assign extra/minor characters from other projects here and there so that they have have lines while they wait. But if they are not, I thought giving a heads up would only be fair that there would be a long wait in-between comic lines.

Several years ago, Arlecchino, who had grown up in the House of the Hearth(an orphanage), challenged the previous holder of the Knave title and ended up succeeding her. She reworked the House of the Hearth; and while strict, she allowed its members to complete tasks their own way and did not punish them as severely as her predecessor. 

Once children raised in the House of the Hearth grow up, those who are deemed to "have potential" are enlisted in the Fatui and are dispatched as agents to other nations to await orders. They may also end up as Arlecchino's agents or as the subordinates of other Harbingers and perform assignments other than espionage. Arlecchino is referred to as "Father" by orphans within the House of the Hearth, with the orphans considering themselves children of the Tsarista(cry archon).

Voice: Would love to voice match Erin Yvette, also open to your general interpretation of the character(something medium to the deep range while being sneaky/cunning also works)!
