My idea is a silver crown. This game has a diverse array of themes, it's not all technological and even if it were, who says you can't have castles, kingdoms and kings or queens in space? Why silver? Because gold is overrated and tired. Silver is pure, non-toxic and even has healing properties. It symbolizes purity and power, pristine quality, reflecting your true self in its mirrored glow. Here are a couple rough drafts I've just made to help people visualize my idea: There could even be jewels in the crown such as the one above. Imagine sitting on a throne atop your vast empire and flashing your crown to your subjects so that they all know who's in charge, who's the boss. The story would be yours to tell, there doesn't need to be simply one background for any given item, let alone this one. Personally, the lore behind this crown for me follows the tale of a civilization lead by an up-and-comer soldier who rises through the ranks of the government on his home world until he has reached a position of great power in his political system, changing the very infrastructure of the planet, altering titles and taking up the new Silver Crown as a sign of his new rule over the people. The Silver Crown would be the icon for the freedom and progress of his people, drawn on flags and appearing on logos across the galaxy as a sign that his rule has reached you. When people spot the king, the first thing they notice is his shining silver crown and they know immediately who he is.
