Ooh, if it is Chiulder, I wonder what he would want with Leion. Or is the whole thing, and the reason he might be chasing him, just to keep him from making more trouble for them?

One quick note:

"There was probably nothing of interest here anyway, and if it did seem likely to warrant a more thorough search became too dangerous for him to go further, he would get out and leave it to Tana."

It looks like there's an "and" (or maybe "or") missing between "search" and "became".
