After hitting Bartertown, WargamerAU and CCM mailing lists, i'm slowly getting a decent sized Rogue Trader Eldar force assembled to fill in the story line for Craftworld Dras'Volharr.
Before I go any further, if anyone has batches of old Guardians to offload - please get in touch as I am actively looking to fill out these squads :)
To give you a snipet of information, the Warhost is sent to a former Maiden world, now desolate, to investigate a long lost Eldar Starport. If you're thinking "Hey, that sounds alot like the 8x6 table being built", you would be right. An Ancient Bone Singer to repair a damaged Webway Portal, and Whiteseer of the Black Library to reactivate it, play significant roles in releasing the Rogue Trader era Eldar trapped in limbo, all due to the portal being damaged before reintegration occurs.
In short, a reunion of new and old Eldar ensues, providing a reason for all editions of Eldar to be displayed as a single unified force. You're probably saying "Screw the story, show me the goodies!", by now right? Well ok then...
