Oh this is a gem of a story
Any chance of a sequel? (cue X-Files music!)

Very entertaining, a good read.

That was awesome! Too funny.

I enjoyed reading it.

Your spelling, vocabulary and punctuation are very good.

The story changes point-of-view several times, and I found this a little confusing. It is good to see things from both the elf and human perspectives, but you need to make the shifts a little less abrupt.

You might want to edit the first part for tense and/or voice. I think this is a case of the old adage "show, don't tell." For example, write "Riddit scrambled through the winding passage" instead of "Riddit had scrambled through the passage." Instead of "He knew almost instantly that he'd entered the wrong passage" you could write "He'd known almost instantly that he'd entered the wrong passage." You are telling us what he has done, instead of showing us.

I thought that the action scene at the end was well-written.

Riddit "wasn't good in battle." Drow warriors who aren't good don't last long. Sounds to me like he is more of a rogue?

The woman is just as important to the story as Riddit. Maybe give her a name?

I'd rather read about Riddit's adventures in the Realms, but a real-world crossover is an interesting idea.

Lots of possibilities for a Chapter 2! I enjoyed reading it. Hope this helps.
