So, have two questions, both kind of pointless, but they had my curiosity. First, are voidships often painted? I have seen Battlefleet Gothic ships, and many of them are often painted, like 40K minis are, but while I might see the different colors of the Astartes armors serving a purpose, painting a two mile long ship would just seem superfluous, even by RT standards of practices, and much like the Golden Gate Bridge, someone would have to be doing touch-ups year round. One of my RT's important colors is green. Would his ship be a big gray slab in space? A gray slab with some green lines and panels? A green slab? One of those little things where comparing the RPG to the TT minis game might fail me. I don't know if most Chaos ships in RT are just red for the hell of it, or big metal slabs of steel colors. If Eldar ships are often light blue, or if they are dark colors, to help blend with the space backdrop.
Second, how much do Eldar really value individual lives among their race? I know that they'll willingly sacrifice millions of Humans to save a small amount of Eldar, when they can, but how much "insubordination will they tolerate from their own? If they kill traitors, they can collect their soulstones, and it's a step closer to the Ynnead Plan, but they seem to preserve Eldar life, and don't take every opportunity to kill DE, which are all traitorous a-holes. Would they simply try to curtail the renegades' actions, and let them live, or eliminate them as a threat to the rest of their people?
