GROMHURAN
Ancient Great Horned Dragon first witnessed in battle with the Gromek captors of CrIsis, see log ‘It is always darkest before the dawn’ and ‘Gromeks and Gods’.
Later he meets the group at the crest of the Baalgor Mountains and shows them a quicker way down in exchange for a vow of their return in 3 weeks with a runic item from Xerx’ses home. See the posts There and Back Again, Through the Looking Glass, and Ceptaculum pro Vim Psychicae in Potentia.
