Ferifax Arch

The Ferifax Arch was designed by Vulpitanian thaumaturgist Egdelwon Klive, as a proposal to King Adler Sartoriusson's Commission on Population Concerns. The Arch would infuse returning changelings with lowfolk vitality (and increased fertility) by bonding them with the spiritual essence of a lowfolk swapling. The resultant being would be a half-elven, half-lowfolk hybrid called a "crossling."

King Adler rejected this plan as Unseelie, because it required that the swaplings be killed. However, his son Gawain instituted the plan and commissioned Egdelwon's son, Evan Klive, to carry out construction of the Arch.

Certain shadowy groups (such as F.E.L.F. and the Sisterhood) regarded crosslings as an abomination. It was speculated that the true purpose of the arch was not to bolster elfkind's flagging fertility rates, but rather to discredit the Imperial Court by simultaneously depriving it of its elfliness and embroiling it in an Unseelie scandal. All such speculation came to an end when the Arch was destroyed by persons unknown in an act of sabotage.
