Well, there are so-called "reverse dictionaries" such as this one (and searching for "soul guide afterlife" returns "psychopomp" as the top result). That being said, I doubt many people know that they even exist. Plus, we already have quite a few questions tagged "single-word-requests", and so far, they are not getting close-voted at all. In fact, they are quite fun, while at the same time not being fun for fun's sake. They are fun and challenging, and people can learn from them a lot (as opposed to fun questions such as "what is your favorite punctuation mark?").
