From one of the abandoned crates, discarded now because of its weight and its putative lack of utility
From one of the abandoned crates, discarded now because of its weight and its putative lack of utility, I spilled a quantity of chains to the grass. They were Harl rings, named for the slaver Harl of Turia, who is reported to have first used them. They consist, in effect, of four portions.
First, there is a metal ankle ring, which snaps about the girl’s ankle.
Second, to the back of the ring, there is welded a closed loop.
Third, to the front of the ring, fastened through another closed loop, is about a yard of chain.
Fourth, this chain terminates in a locking device, which may then be snapped shut, if one wishes, through the welded, closed loop on the back of a second ankle ring.
The Harl ring is a versatile piece of custodial hardware. It may be used to chain a girl to anything, the ankle ring closed on her ankle, and the locking device at the termination of the device being easily fastened, looped, say, about a tree, or stanchion, or the ankle of another girl, and then locked about its own chain, or through one of the links of its own chain.
The chain, of course, may also be looped about, say, a tree, or a pillar in a public building, and the locking device snapped into the welded ring on the, back of the girl’s own ankle ring. This is called a closed Harl Loop.
One of the most frequent uses of the Harl ring, of course, is to form a segment in a slave chain, which may then be of any length, adding or removing girls, as short or as long as the slaver wishes
