Death could be viewed as part of the cycle of life...
I was thinking of giving Silhouette some resonance with a sort of druidic/Celtic "Three-Faced Goddess," due to her shifting nature.
Though honestly, Death as it applies to corpses and afterlife and underworld feels more like an Ubariya thing to me.
Oh! Also, I'm planning on making Silhouette's mortal clergy druids instead of clerics, in general. When you think about it, it's a perfect fit. Druids have bonuses to resist fey magic, they gain druidic spells...which is what Silhouette casts...and they gain Wild Shape, which is really just a scaled-down version of Silhouette's much more flexible and powerful Alternate Form ability. They even use the same underlying rules.
In her guise as huntress, she gets some rangers too...and in her aspect as fortune and luck, she gets some bards and rogues.
