A while ago I did a picture of Krynn, a Vorlon character who I made after watching a TON of babylon five. Vorlons are one of the first races to ever have existed, and they have evolved so far that they now exist as energy suceptable to the perceptions of others, they appear differently to everyone based off of their faith and beleives. So to keep down the confusion and to cut down on the strain it puts on them to exist in our atmsphere (theirs is methane) they wear encounter suits that make them appear the same to everyone and supplies them with their natural environment.

Krynn was a character I played for a little while in an RP, a Vorlon who awoke after years of hibernation long after the rest of the race had left. Though in the Babylon 5 show you never see a Vorlon who's name is not Kosh, Krynn has a different name to distinguish himself from those whom have already gone beyond the rim.

The quote is actually from the show and Ambassador Kosh himself said it to Captain Sheridan before he took him in to training.
