So this would be the Better Day At Blackrock, presumably ?

I prefer to stick with an appropriate adhesive. ?

There are ancient examples of the legged triskelion as well, from Greek art, for instance, while such "rotary" symbols more generally go back far into the millennia BCE, commonly with three or four "arms".

I fear someone will have suggested this already, but will there be a seal with a seal on? Or even a walrus? ?

Thanks Ralf - that all seems fine now! Odd it should just have been those two symbols out of the entire set. Teleported away perhaps ?

I can hear the complaints of the neighbours already - can't even see the stars at night now for those rich folk with their millions of candles and magic sources spilling waste light everywhere ?

@Loopysue - Since Mist & Fog's an alchemist, the variant smoke colour may be the point there.

Might even be a case for a Sheet with an even stronger light source emanating from that house in one of those "oops" moments?!
