From the Forward:
This is my 5th adventure designed for the purpose of pitting high level parties against giant adversaries. The previous scenarios, Sanctum of the Stone Giant Lord, Castle of the Cloud Giant Queen, Forge of the Fomorian Smith Lord, and Giants in the Deep, are (were) designed to be supplemental adventures for
characters of more experience, more savvy, and having a desire to continue hunting giants and their kin. While all can be played as separate adventures, they can also be linked with some minor creative writing by the DM. There is already a storyline connecting the G5 to the G6, and another linking the G7 to this one; subtle as they are.
