I'm stealing the SeaFox avatar for now. O0
As far as important things the SeaFoxes have done (someone had asked earlier in the thread), well, they were the clan that developed the modern Iron Womb, so their role in Clan history is pretty huge for that alone.
Hope they have an interesting role in the future. As information vendors as well as merchants of finer war machines/accessories, they fill a role as well as perpetuate it when the situation demands it.
