Not all mass relays need a connecting
end at the other side. The major relays that let you jump a long
distance do, but there are smaller relays that are omnidirectional and
can't throw you as far as the large ones. Presumably, the Reapers got
out there by assembling a series of 'non-paired' relays.
Primary relays are in pairs, & cover very long distances. You can only go from one end of the pair to the other end.
Secondary relays are omnidirectional, & do not cover distances as long as primary relays cover. But they still need to connect to another relay at the other end - you just have a choice of secondary relay destinations, instead of being limited to only one destination like with a primary relay.
http://masseffect.wi...iki/Mass_relays"There are two kinds of mass relay, primary and secondary. Primary
relays can send a ship hundreds of light years but only link to one
other relay, its 'partner'. Secondary relays can link to any other
relay over shorter distances."

See post above. If they had a mass relay out there with them, they'd have used it and be here by now.
Mass Relays create a corridor of mass-free space, according to the Codex. The range of that corridor would have a limit. Nothing says that the corridor needs to be one way. Citadel relay creates the corridor, and the Reapers enter into it from their end.
The two-end relays just give a stable end-point for the corridors, rather than blasting it through a planet or star beyond the intended end-point to devastating effect. Being in Darkspace, that is not such an issue, the corridor isn't going to impact a planet/star.
That doesn't fit with what we have been told about relays though: Whether primary or secondary, you still always go from one relay to another relay.
Reason to have not used the dark space relay if they had one? It is a primary relay (or super primary relay given the vast distance) , with its
partner being the Citadel relay... With the Citadel relay inactive, they cannot use the darkspace relay. The two are linked, like all other primary relays. And like all other primary relays, you cannot choose from multiple destination relays, only the partner relay can be travelled to.
