Las Vegas

Las Vegas, also known as Sin City, is a famous city and tourist site in the state of Nevada. Surrounded by desert, Las Vegas is both an oasis and a city of pleasures, primarily gambling. Signal and Sigil both consider this city their home; other than them, they are possibly the only meta-humans living within the city.

Landmarks
The hell are you talking about, the whole city is a landmark (the city itself is ironically very boring if you're not going there to gamble or party)

Notable to the plot is the Golden Nugget Casino. Both of Lucy's parents work there: her father Marcus works as a bartender and her mother Danita as a dealer at one of the blackjack tables.

"Lord Signal" Arc
At least three supers have visited this city in search of answers concering the city's primarily known super, Lucy "Signal" Lagrange.

The first was Synapse, under the alias of Nicholas Eniac. Sigil personally greets him and answers any questions he may have on her cousin. He leaves to the Golden Nugget hotel to further question Marcus since he was a witness to how and when Signal first received her powers.

The second was Saho Mange, though what he did was less "detective work" and more "digging through someone's trash." He didn't find out as much information on Signal as he wanted, though for a good reason: Vegas' third super guest, Vladimir Valencruz.

When he arrived to Vegas, it was to massacre Signal's parents along with the rest of the Golden Nugget patrons and workers. By the time news gets to Signal and she flies off to Vegas, the city has been thrown into a rioting panic and Valencruz has both recruited several people under him as well as create some ghouls. The fight between Signal and Valencruz ensues along with the help of Saho and Sigil who provide Signal a silver leaf-tipped tree as a makeshift stake.

While a second Eagleopolis situation has been avoided in Vegas, the resulting destruction of the riot and the Golden Nugget massacre will not be forgotten from the minds of those who live in the city.
