Description 

How it all begun
The O'Reilly’s is an Irish gang formed by the twin sisters Niamh and Aoibheann O'Reilly. After the violent death of their parents in a failed robbery at their seaside estate in Cork, Ireland, the sisters were left with nothing but a fractured legacy and a will to survive. What began as a desperate attempt to protect their younger brother Cillian and hold onto the scraps of their family’s name soon evolved into something far more dangerous.

Niamh, cold and calculating, and Aoibheann, fiery and fearless, began recruiting loyal followers, thieves, brawlers, and survivors who had been cast out by Cork’s criminal elite. United by hardship and the sisters’ unrelenting vision, they built a tightly-knit syndicate that became feared throughout southern Ireland.

History 

New start, 1904
By 1904, with enemies closing in and ambition boiling over, the O'Reilly's sailed to New Alexandria. Now based in Saint Denis, the gang is laying down roots, aiming to rise once more, not as aristocrats, but as kings and queens of the underworld.

After getting their footing in the state the O'Reilly's started picking up strays, recruiting these petty criminals into their gang. Slowly but surely becoming one of the biggest gangs in all of New Alexandria. Nobody will take them down, even if they try their hardest to do so.

At the end of June the gang leaders decided to move the whole gang from Saint Denis to Emerald. So the whole gang moved their stuff, their business and their belongings over to Emerald. Even renamed their Irish Pub to The Soggy Boot instead of Doyle's Tavern since it wouldn't make sense to keep that name if they're not in Saint Denis anymore. Emerald simply fit them better than the swampy Saint Denis.

In July the O'Reilly's declared war against the Red Renegades who'd been causing trouble around Emerald. Which the O'Reilly's of course did not appreciate. So Niamh O'Reilly sent out a letter across the state warning them to stay away or the O'Reilly's will put them five feet below.

Middle of July Niamh, Cillian, Atticus and Colby were in a shootout with law and bounty hunters at the Oil Fields in the Heartlands. The shootout kept going for ages, in the end only Niamh was left standing. She attempted to save her fellow gang members but was ultimately shot down. The four of them were sent to Sisika, the first time for Niamh O’Reilly to get caught.

Late July the gang made allias out of the Blue Spades, a gang that resides in Thieves Landing. Both gangs agreeing to give each other information about their territories. O'Reilly's being out East and Blue Spades being out West, meaning the have the whole state covered together. Niamh and Ezekiel DeWitt (Leader of the Blue Spades) exchanged some information over drinks in Thieves Landing and made the alliance there and then. Niamh gave Ezekiel an old pocket watch as a sort of promise to keep this information sharing going.

Charles Andersen if the first member to leave the gang by his own accord, but he did it in a very respectful way by sending a nice letter to Niamh. Usually the gang leaders would rough up anyone who abandoned the gang, but since Charlie did it in a good way Niamh settled with just giving him a little slap.

Trivia 

The gang has an Irish Pub they run, it's called The Soggy Boot.

The gang motto is whispered rather than shouted: “Luck is on our side.”

Niamh is rumored to keep a ledger of every enemy they’ve ever made. No one knows if it’s real, but she sometimes refers to it as “the future.”

The twins often argue in Irish Gaelic when they don’t want their crew to understand them, especially during planning.

The twin sisters younger brother Cillian is off-limits. Any harm or disrespect toward him is considered an automatic death sentence.

Gang members never whistle indoors, an old Irish superstition carried from Cork that’s become gang tradition.

Everyone in the gang has a nickname, usually chosen themselves, but sometimes given by the twins.
