Easy enough to kill him outside his cottage, a passing dragon also tried for a little while but I had to finish him off.

Just thought though.... was this a mistake. He was some sort of mage with a well-equipped cottage inside.

No, he attacked as soon as I walked in too.

I killed him 3 times, but my 4th Character just walked past his cottage. I mean, I'm the intruder here, what right do I have to just enter some strange house? LOL Good Drelas lives in peace now hahahaha

I never used to mess with him, but then one of the modders set his cottage up so it works as a player-house....

Drelas is pretty unimportant. You might be directed to his cottage to fetch something for a certain quest, but it doesn't appear to matter whether he's already dead when you do so.

I hope he's not important as I killed him earlier, just killed a dragon and then noticed his hut. Soon as I entered he attacked me, nearly killed me too as I hadn't healed myself after the battle with the dragon.

LOL nah, that fetcher isn't important!
