Okay girls, don't laugh at me, but this is the first thing that popped into my head: an acorn.
At first , I thought it was good because its along the same theme as Skiouros and our 'autumn tints.'

I also liked it because the acorn grows into a tree, which is strong but still shelters everyone underneath it.
But then I did a quick yahoo search on the symbolism behind the acorn. It symbolizes: authority, victory, and maturity. In ancient Celtic times it was the ultimate symbol of potential, fertility and immortality.
Pretty cool, huh?
