First of all, I don't have the book(s) on me atm, so my question may prove imprecise. Should it be so, I'll try and fix it asap.

As far as I can remember, not all Cainites (vampires) have some kind of night vision in Vampire: The Dark Ages. Quite the contrary. However, during the period covered by the game, the only means of making light was to use fire (candles, torches, chandeliers, and so on.) However, the rules say that vampires have a debilitating fear of fire (Rötschreck), which is rather hard to resist and overcome. So:

How do vampires without night-vision stay "alive" in and navigate the World of Fire-lit Darkness? :)

Sure, they can stay as far from the fires as possible, having their minions light and carry the fire-based light sources, but I think that proves pretty awkward (not to mention unsafe) in any number of situations, conflicts, etc. Of course, larger cities will have some rudimentary form of street lighting, and the Moon (and the stars) will also provide at least a bare minimum of light in the open... but what about all the catacombs, dungeons, castle and fortress interiors, etc.?

Are there rules in V:TDA (any edition) that answer this problem? (Easier Rötschreck than what we had in V:TM, and so on.) How is it best to handle this in a game?
