(Another piece of food for thought for you all, while the vote is in progress.)
A little sneak peek into what the Craftworlds are doing at this stage in M42.
- Craftworld Alaitoc - Currently present in the Ultima Segmentum, Alaitoc is tailing Iyanden like a hawk, determined to safeguard it from any threats.
- Craftworld Biel-Tan - Biel-Tan is currently in the Tempestus Segmentum, trying to recover its strength after a series of bruising battles with the Tyranids of Hive Fleet Leviathan.
- Craftworld Iyanden - Iyanden is hovering around the borders of the T'au Empire in the Ultima Segmentum, with Alaitoc some distance away. They are trying to avoid major combat for now.
- Craftworld Saim-Hann - The Wild Host is currently in the Pacificus Segmentum, engaged in a bitter, dangerous hit-and-run campaign against the forces of Chaos and the ancillary tendrils of Hive Fleet Leviathan, with valuable assistance from Yllentoc. While being successful for the most part, they will pull out of the region should the situation spiral out of control.
- Craftworld Ulthwé - The Song of Ulthanash is maintaining a thankless vigil near the Eye of Terror.
- Craftworld Yllentoc¹ - Currently present in the Pacificus Segmentum, Yllentoc is engaging in a high-risk hit-and-run campaign against the forces of Chaos and the ancillary tendrils of Hive Fleet Leviathan, in support of Saim-Hann. In spite of their successes, their Farseer, Irliraniel, is chafing at what she sees as a wasteful and distractionary campaign and is busy making plans for pulling out of the Segmentum.
1.Yllentoc is a Craftworld of a scale similar to Alaitoc, Biel-Tan, Iyanden, Saim-Hann and Ulthwé.
Much like Saim-Hann, this Craftworld fled the homeworlds of the Eldar prior to the birth of "She Who Thirsts", and developed the Path with a degree of flexibility.
They have kept in touch with the Exodites, as well as several of the smaller Craftworlds.
They have been in the thick of conflict very often ever since the Fall of the Eldar, with several battles fought against the Orks and the forces of Chaos, as well as the Drukhari. They will attack the Imperium only if they are proving to be a significant threat to the Eldar (like taking over a Maiden World, desecrating Eldar ruins on a world, or to help retrieve the remains of and resurrect Phoenix Lord Irillyth on Bethalmae). They have fought the Tyranids on quite a few occasions, and usually prefer not to engage them, but when they do, they try to inflict as much damage as they can.
Unlike most Eldar, the Asuryani of Yllentoc have no illusions as to the fact that the Eldar Empire is gone, probably for good. They are thus, fighting to secure a region/regions of the galaxy where the Eldar might live in peace. They are also more likely than other Craftworlds to co-operate with lesser races if it brings them benefits, and also averse to going on genocidal purges against them, seeing such endeavors as mere distractions.
Due to the similarity in their culture with Saim-Hann, they have warm relations with that Craftworld, and consequently, bad relations with the others (except Iyanden, who they helped out a few times, and Ulthwé, who doesn't see them as a threat). However, they are liked by quite a few of the minor Craftworlds, due to having helped them in some way or the other. They are quite proud (but never arrogant), and respect the value of honor.
Their relations with Biel-Tan are the worst (bordering on hostilities). It is due to them not being genocidal, and also due to rejecting the Ynnari.
Their color scheme is: Purple body armor, Red helmets, White faceplates. Their rune is a spear placed upright, with purple and red coloration in the background.
