So, I heard awhile back that theres a Light house with a Kahjit keeper. Anyone know where?
I know Solitude's lighthouse (north of the city, just follow the road along the coast) has a Khajiit keeper. It's the lighthouse you need to pay a visit for a quest from an Argonian.
If you've got a follower and want light without using up your torches, give one torch to your follower. He/she will equip it immediately when it's night or when you're inside a ruin/..., and it'll be one of the eternal kind (until you take it back of course).
Not sure if it's really such an interesting thing: when you force Naris the Wicked into the very cell he's standing in front of and lower the gate again, thus trapping him, he'll still be trapped in there when you come back at a later time (provided you didn't kill him). Unfortunately, he didn't seem to be very impressed by it.
