No, no one else. I'm puzzled.
You got the quest in your log book (king)
You're informed via logbook where
you're informed about the forging (Grisha)
you've got the dragonheart
and Patrick is silent...
I have no clue, sorry.
Is the letter in your inventory or gone? Some gamers had to throw this and the Axe into the Hall so the Dwarven King would get it.
A last try: Mpenzak has something to say about this armour, too - the trader in Verdistis - do you recall a speech option( convers. logbook?)
