What do the Lunars want in Dragon Pass, anyway?

     Forgive me if this is a bit of a newbie question, but, as the title 
     says, what do they want there, anyway?  From my viewpoint:
     


     * Peloria has never been occupied by DP

     * Pelorian involvement in DP has always led to maximum harm to Peloria 

     (e.g., Dragonkill war, fall of the Bright empire)


     * Peloria has repeatedly been invaded from out near Pent (first age 

     rule, Sheng Selaris)
     
     From my perspective, based on history, DP (and the Orlanthi in 
     general) offer very little active threat when avoided, and a great 
     deal of risk if disturbed.  Pent, on the other hand, represents a 
     continuous, active threat.
     
     Am I missing something?  In general, what is the motivation of the 
     leaders (Emperor, Bellex Maximus, whomever) for invading DP?
     
     The only motivation that I can perceive is a need for the Red Goddess 
     to defeat Orlanth for control of the middle air, and to integrate 
     Orlanth into the Lunar way.  Is this an accurate view?  If so, what 
     would the mytho-religious effect of that be?
