I hate to steal this from Sav, but in the interest of a prompt reply...
 * Yes, it's permissible, if used appropriately in context.
 * 1) You can find a great summary here, but in short, past perfect is used when comparing two events, both in the past, to refer to the one that came earlier.

Here is an example. Take , when Han, Leia, and Chewbacca are on Cloud City. Leia goes in to talk to Han about C-3PO's disappearance. If I was writing that scene (without dialogue), I might write:


 * Leia expressed her concern about 3PO's absence; they had lost him days earlier.

The italicized text is past; the bolded text is past perfect. Both happened in "the past" (since Star Wars takes place "A long time ago", everything is written in at least the past), but losing 3PO happened earlier than Leia expressing concern about it, so the past perfect is used to compare the two.

Hope this helps.
