After the Black Death struck Essen, nearly half the city's population was wiped out. A Templar offshoot called the Brothers of the Cross travelled across Germany offering protection from the plague, though they were secretly looking for the Ankh, a Precursor artifact. In 1350, the Brothers of the Cross and the Assassin Lukas Zurburg mysteriously vanished.
In May 2014, Master Templar Juhani Otso Berg travelled to Essen in search of the Ankh. After consulting with Violet da Costa, Berg concluded that the Ankh may not be a real artifact but a trap set by the Assassins. Berg decided to abandon his search, but told Violet to keep an eye out for possible leads related to the Ankh.
