Eldar Craftworlds (Warhammer 40,000) - Iyanden

The Iyanden Craftworld was once one of the largest and most prosperous of all the remaining Eldar craftworlds. They barely survived an attack by the Tyranid Hive Fleet Kraken, which nearly destroyed the Craftworld and killed four-fifths of its population. On the verge of total annihilation, Iyanden was saved from complete destruction by the exiled Prince Yriel, who had formerly been the High Admiral of the Iyanden fleet. Yriel and his exile pirate raiders, even though previously vowing never to return to Iyanden, could not bear to have their craftworld destroyed and launched an attack on the Tyranid fleet. Taking the final battle to the craftworld itself, Yriel used an ancient artefact spear called "The Spear of Twilight" to slay the Hive Tyrant that led the assault. In doing so, Yriel doomed himself to a slow and painful death due to the psychic artifact being bound to its user and burning their soul. For now however, the forceshield worn by Yriel staves off the constant energies of the spear. Regardless of his actions, the chances of Iyanden recovering from its losses are slim and their future looks bleak.
