The web team for the Lord of the Rings Online has published another of their Exploring Middle-earth articles. The focus of this installment is the 'Gwindethrond'.

Deep within the folded lands along the shores of Nenuial, known to most as Lake Evendim, lies a grotto, its entrance hidden behind a waterfall – but this is no ordinary cave, for it is home to Gwindeth, the Blue Lady of Evendim. Who or what she is remains a mystery, but she has dwelt at Gwindethrond for many an age, and was a friend to the Kings of Arnor, from Elendil to Amlaith of Fornost, the first King of Arthedain. Some believe she is kin to the River-maidens – though her temperament is much stronger than theirs – or perhaps even one of the messengers of the Valar who chose long ago to remain in Middle-earth.
