The white symbols at the bottom right say 'house spiral' (carefully translated as I could.)
The triangle is a highly stylized triple spiral (Triskelion) an adopted symbol of house spiral since forever, sometimes associated with the spirit of a wolf pack, our group spirit animal. (This is heavily associated with the Celts, but the spirals original meanings if any, are pre-date history as we know it. Like so they many things. They mean what we choose them to mean. (Could spend a lifetime researching spirals)
It also looks like a triple pointed star of the words of House Spiral (another house spiral adopted symbol) I mean the points to stand for starting from the bottom left, Earth (Truth), Water (Kindness), top point - Fire (Courage).
All Ideas to live by. Courage being placed slightly above the others but only there honorably if supported by truth and kindness. Not always easy to put into practice.
The crossed ceremonial daqtag knives symbolizing both honor and death challenges. (Life is a struggle suck it up.)
The tribal house spiral triskelion also just looks cool and reminded me of Klingons.
The skull translates as 'To Be or Not to Be' from Hamlet. Google that, it doesn't get much gothy black darker than what he's contemplating in that stanza. Thus the bewildered spiral crazy eyes seemed appropriate.
Interestingly the language has no 'to be' so the spirit of the translation is something like Survive or Do not Survive.
Hrmm. That's a pretty good covers all the basic overlapping philosophical ideas of what we are trying to do with HouseSpiral.com and Patreon.com/HouseSpiral <-- monthly house spiral cards incoming and membership cards.
