The Devils Den Armory went away after the person who played the owner (Lucian) poofed, the building is now just considered abandoned and is used as a home base of sorts for Raven the werewolf who used to work there, she and her friends occasionally hang out there.

Syn the vampire bar was burned down when Tetradore and Tobias, werepanther and wereleopard, finally got sick of being Risques pets, decided they were going to end it once and for all and with the help of Isolt, a vampire Risque made against her will, the trio burned the bar to the ground and took off, finally escaping their imprisonment. Tet and Tobi gathered a pack together and took over the Westside where they now run the Ark which dabbles in a lot of the black market kinda stuff as well as cage fighting,a bar etc

I hope that answered your questions! :D
