Present Ghelryn's letter of recommendation to King Morinn or Queen Tithmel

As a reward for defeating the stone giants attacking his forge, Ghelryn writes the characters a letter of recommendation (see the “Marks of Prestige” section in chapter 7 of the Dungeon Master’s Guide) and suggests they present it to King Morinn or Queen Tithmel should they find themselves in Citadel Felbarr.

Ironslag should be nearby as well if the party comes here...
