Wolfram & Hart, Attorneys at Law was a powerful international and interdimensional law firm.
Wolfram & Hart, and its many incarnations in other dimensions, was actually a front organization for the Wolf, Ram and Hart, an ancient cabal of demons known euphemistically as the "Senior Partners" who worked through their powerful principal agents—the Circle of the Black Thorn.
Wolfram & Hart branches, such as the Los Angeles branch, were created over unconsecrated ground. As of 2004, the firm had branches in every major city in the world, as well as satellite offices in many areas of the world where they helped spread oppression and evil.
Due to its supernatural nature, branches of the firm could be rebuilt or restaffed rather quickly, such as when the Los Angeles branch was completely destroyed by the Beast. The entire staff—according to Lilah, even employees out sick—were slaughtered and the building heavily damaged. Within days, it was back to operating condition with the entire staff replaced.
