I agree with Echo in saying that you brought across the nature of the Kumbra well. I noticed a few points where you mixed your pronouns, at one point referring to Shek-Ta as "her, at another as "it". You also made a grammatical mistake, the possessive it "its", "it's" means "it is". A nice well rounded sub,Silv. Go to Comment
This is a solid mini-adventure! Though I am expecting to see the mystery machine make an appearance :)
That said - you have a few missing capitalizations at the start of sentances, and a few spacing issues. There is also still a bit of overlong sentances. Read them aloud to yourself, and if you find yourself running out of breath, rebuild your sentences. Go to Comment
Orcs record their deeds through symbolic mutilation, scarring and tattoo. Perhaps creating the medium of skin as art, which humans followed later. Perhaps tattoos remind the elves of orcs and make them angry...
