so how big are those ships
like
in reference to other ships
like compared to a death star
Gloriana class battleships were around 20km in length and the Abyss class "easily eclipsed them". Death Star had a diameter of 160-180km and the Super Star destroyer Vader had was a puny 1.6km.
Been away for awhile, what is going on with this Primaris stuff? Is it a soft reboot of the entire SM line to truescale?
Basically, yeah. In-universe they are a contingency measure set by Guilliman that Archmagos Cawl has been working on for the past ten millennia. Stronger, faster and larger than regular marines and some heavy tech-heresy.
