Sanctuary Council,
My name is Dusty. Mycopolis is dead. In its place is Clan Slugcrawl, goblin worshippers of a Great Slug and its slug-like Legend Race. The people there were killed, throats slit, one and all. I am told their leader, Mynolee or some such, is not there.
Slugcrawl says they came from a place where there was no more food, to a place where there is much food; Mycopolis. The Great Slug led them there. They prepare, feed, and multiply, awaiting their Legend Race. They expect us to bow to this Great Slug or we will feel its wrath.
You will need a large force as the goblins number in the hundreds. Some of your Spellguard and maybe 20 of your Watchmen, well prepared, should be able to handle it. Their chief and prophet killed me with a single spell, so prepare for that as well.
If you do not, then eventually that which killed Mycopolis will kill this city as well, when Mycopolis runs out of fish.
