From the campaign:
We were preparing an update with the new concept art, to show you another unit of the Guardians of Tanaor starter pack: the Exiled. But breaking news stopped that plan.
We want to share the works on the fifth faction. We did not plan to release this on the KS, but the incredible work that Mati is doing in his collaboration is going to permit that addition, automatically unlocking its choice as eligible faction for the starter packs and as addon.
Here you have the first looks of the modeled miniatures being finished
