Eldrich Omens
There's a lot to be said about this excellent Battlebox - and it won't be long until you get your hands on the 16 miniatures, split into two forces. 15 of them are brand new and currently only available in this box, and one is a classic Forgefiend that you can also build as a melee-focused Maulerfiend.
The Aeldari half is commanded by the new multi-part Autarch. This unparalleled warrior has a grab bag of equipment options to suit one who has walked every path of the warrior and emerged with the skills to pay the bills.
They are supported by five new Rangers, complete with chameleonic cloaks, nasty long rifles, and a wide array of gear. Three Shroud Runners add a shot of mobility, putting Rangers on swift new Raptor Jetbikes to hunt targets before screaming into the distance.
The Aeldari will need all this new technology and more because they are dealing with a nefarious Warpsmith. This insidious engineer is a dark mirror of the Imperium's revered Techmarines, covered in all sorts of evil mechatendrils, spikes, and industrial adornments.
The story behind this box ties into the current Nachmund season of Warhammer 40,000, and it's also an excellent starting point for getting into both armies and a great narrative hook for the current season.
