Four major groups are in Eregion such as the Elves of Rivendell, the Dwarves of Moria, Dunlendings and Half-Orcs.
Due to two reasons, the Elves of Rivendell are hereFrom the south, Dunlendings and Half-Orcs who serve Saruman have come up from the Gap of Rohan, and they threaten to encompass all lands south of the TrollshawsThe elves of Rivendell wish to prevent the advance of the forces of Saruman, and additionally wish to cover the tracks of the Fellowship, assuring that the enemy does not know where the fellowship went
Here the Dwarves of Moria are to re-open the Mines, having heard nothing of Lord Balin and his expeditionThey are not found in the majority of Eregion, instead only near Moria, at the south-east edge of the region.
Under false pretenses, the Dunlendings have been ledWhile the uncouth people are at war with the free people bucause of the lies of Saruman, who has convinced them they are mistreated by othersAs such, they work with the half Orcs and their wary allies who directly work for Saruman hand by hand
Directly the Half-Orcs are here for SarumanThey take an interest in finding out if the Ring is in Rivendell or moving, and work with and use the Dunlendings for this
Eregion consists of two sections, one is Glad Ereg and another is Pend EregionGlad Ereg is a broad region ranging north from Gwingris, sweeping south-east through a wooded, hilly region toward Red Horn PassThis region is thickly inhabited by giant fire-flies, wood trolls and huornsAt Glad Ereg is the first outpost of the elves here, an ancient ruin called GwingrisThis should be the first stop for any visitor to Eregion from the north.  At Gwingris you can find supplies, a healer, and a stable-masterTo use fast travel you will need to do deeds for quests in Eregion, once you have done most of the quests in Eregion, you will be able to fast travel all through EregionAll of Pend Eregion is inhabited by wyrms and crebain, the latter spies of Sarumen.  Northern Pend Eregion, near the road from Giant Valley, is an area called Lhugres (38.8S, 6.8W), a lair of the lizard-like wyrms of Pend Eregion
There are two ways to get to Eregion from the north.
As one of the way to Eregion is via Tal Bruinen in the TrollshawsHere a stable master is being addedFrom Tal Bruinen, head south and cross the Bruinen (38.3S, 14.6W) and head uphill and south until you arrive near Gwingris in Eregion
The other way to Eregion and Gwingris is via the Giant Valley in the upper Trollshaws.  At the southern portion of the Giant Valley (37.2S, 5.7W) you can enter an area called Daergil in the north-eastern portion of Pend EregionThere head south-west following the trail until you reach a fork in the heart of Glad Ereg (42.4S, 13.6W) and take the north-west path to Gwingris.  The path from Tal Bruinen is much faster and safer, as the path through Pend Eregion has dangers from wood trolls, huorns and Dunlendings.
Eregion is worth of exploring and adventuring though it is not large as the north downsThe free people can come to this area, but there is one thing you should note, the most important thing to do is to get enough quests for rapid transit to Echad Gwingris from Echad Dunann, for rapid travel in later levels.
There is a large region named Eregion which is located in the south of the Trollshaws and north of the Mines of the MoriaEregion is the first area you reach when you arrive at the new Mines of Moria contentAnd also it is a large grassy area, moderately forested in it's northern portion, thinly forested to it's southA riverbed travels east to west from Moria to an area called Mirobel in the southern portions of Eregion, this once housed the river known as Sirannon, the gate stream of Moria
