Amphithoe and Esin have proven to inspire a staggering amount of works describing their relationship. Unlike the previously described couples, their depictions fall in two categories: forbidden lovers, who overcame the odds and books focusing on the carnal aspects of their relationship.
The first category has the most well-known representative in Anja Perlex' "Wind in the Seas" (1), which describes their struggle against a harsh society, while ignoring entirely the fact that Uranus' and Neptune's relationship was rarely, if ever, viewed negatively by most Imperial denizens. It has also managed the amazing feat of not mentioning any other Primarch or Senshi during the whole book, which covers a good portion of the Great Crusade, which is an achievement in itself.
Most writers of similar works tend to produce books that focus on suffering and social injustice, which sadly has nothing to do with the reality.
The second category, while decidedly focusing on the more positive aspects of human life, provides as many examples of poor writing as the first. One of the favourites in this group is Brenn France's "The Sight Most Precious" (2), which shies from describing the actual act, but depicts the first meeting of the two Senshi in a highly erotic manner.
Both Senshi had repeatedly decried both depictions as false and Neptune had once gone as far as asking Primarch Fulgrim to write a critical monograph on the topic.
Currently, their relationship has been appropriated by the Adepta Sororita, who focus on their love as a metaphor of the adoration of the most holy human form. "The Lady's Favour" (3), an anonymous work first published in collection of devotional poetry published by the Order of the Martyred Lady, is one of the best known examples of this tendency.
Neither Senshi Neptune, nor Primarch Fulgrim have made any statements regarding the works of the Adepta Sororita.
