See Challenge # 128.

Brainstorming on voidwalkers. My first thought was that they must have some way of getting around other than drakes, but it's probably mysterious and they just appear.

So I decided to try a toned-down version of shadow, where it's slightly evasive. I assume all creatures will have the same voidwalker number (not sure if it should be 1 or 2?).

I thought of when I read about the void, before I read about the outsideres themselves so it's not a perfect fit. I wondered whether to try to ensure the set lists exactly fifteen masks and give them personalities etc but I decided that probably wouldn't work at common, so I assumed common would reference some masked creatures generally, but rare might have references to specific masks, or have masks as objects themselves (somehow if I can think of a mechanic that makes that work without B having all equipment and no creatures).

Flavourful. Hard to picture what effect it'll have on gameplay in limited, if any, but with a mixture of different-sized voidwalkers could be somewhat interesting.

That's a very interesting mechanic.
