I like to use the google 'site:chooseyourstory.com word' search feature. However, numbers as names means I can't really use them, and then Legends is too common a name, and elements aren't all that unique either.
Here is one I did find, Becoming Legend: Third Motivational Thread. (Mizal beat me to it).
It is no longer on sneak preview, and the author is MIA. Further, from my skimming, characters seem to have names, there are wraiths but no mention of wights, and your character can cast lightning, also, I feel illustrations would have been remembered...along with the combat system. Still sharing it because memory is a fickle thing, but without being able to read it, I guess it is a bit pointless.
Trying to search for a charred wight isn't bringing anything up, so I'm going to assume that wasn't the word used...although if the story is no longer published, maybe google won't find it, so I should be using the way back machine or something. (Alternatively, it is very likely that I'm just searching incorrectly, but let's not worry about that).
This is why memorable prose is important, it'll help people find your work years later!
