OK, I finished the Castle and got the "code word" from DeSoto for the Dragon, but how do I talk to him (or her). Everytime I see it I get a face full of fire and it flys away. Any good tips would be appriciated.

You must visit the dragon in his lair to be able to speak to him. Dragon Spire
Do the stout mines first!
Might as well do the Boogre Caves too, if you haven't, just to tidy up the Ishad N'ha quest and all before doing the Spire. You can move onto Brimloch Roon after speaking to the dragon!
