Folium

So I'm going down Parvati's question "Don't Bite The Sun" and stumbled across needing to go to Byzantium. Traveling around planets, talking to people, and finding little information, I do care for my crew, and eventually go online to find the answer. (Glad I did because I wouldn't have otherwise -- This is where the problem ensues) While going through I killed Mr.Bedford, and I was wondering if at any way possible, there was another way to obtain the NavKey to Byzantium. If he had it in the first place, wouldn't it be somewhere kept? However considering general game reasons I could see why it wouldn't just be laying around. Thank you in advance.
