From publisher blurb:
Aye, that’s the report from Ol’ Walloc. Some kind of giant reptile, preying on the farm stock, tearing down fencing, you know how it goes. Along the border lands, o’ course; beast’s no threat to the folk sheltering behind Northgate’s walls. Still, we can’t abandon thems brave enough to face the thuels and Wodon knows what else to feed the city. They tracked the beast to an old ruin about ten miles distant, but didn’t fancy their chances. So the rangers returned, made their report, put the word out. And ‘ere you are.
In BotB, the PCs set off in search of a giant reptile only to discover - well yes a Mutant Reptile Beast - but so much more! Ghosts, giant toads, deadly fungus, a golem, and if they take the time to listen... a tragic tale.
