Askr & Embla were the first humans in norse mythology. Adam and Eve. It was believed back then, that humans were created from trees, given wisdom by Odin. So how does one illustrate that in a logo that needs convey the human, natural and sustainable nature of a company whose goal is to be just that. Friendly, beautiful, natural. With two intertwining trees of course. The fruits of the first humans' love was their children, humanity, and so the love is illustrated with the trees entwined as equals.
