Firstly, am I the only one to think that the description of the Tzenkethi is close to that of the Vorlons without their enviro-suits?
Honestly, I have no idea who the Vorlons are. Never heard of them.
And how does that fit with the depiction of the Tzenkethi from Articles of the Federation?
The Tzenkethi are not physically depicted in Articles of the Federation
, though at least one physical characteristic is noted. I of course strived to be consistent with anything that had ever been mentioned about the species. If I recall correctly, most of the literary information about them came from Iron and Sacrifice
, Day of the Vipers
, and Articles
