A logo contest might be a good idea, but what most of you don't know is the lore behind each and every symbol.
That's a good idea.
Anyway... as already mentioned, there is lots of content to be sourced and there ist always the opportunity to create new content for new symbols/emblems.
For example:
There are more than just Yubos and Mekkis an Atys.
Some Homins might decide on the evil path and worship Kitins or else.
Black Circle has a nice symbol and somehow Homins could use Tribes symbols for their guild symbol.
If not the picture then at least the arrangement of the shape and colour sections. Why not three different colours in on symbol? Or a circle with an inner circle and an outer circle?
