Annihilation Rising (1E)

From publisher blurb:

In Artera, tarasques are more aligned with the French mythological creatures rather than traditional titanic beasts of popular tabletop RPG products. More than one may exist in a world, but more horrifying, they have a lord and master—Monsieur Nerluc.

Monsieur Nerluc clings to the local mountainside. Villagers tell frightened children that the monstrous form of earthen stone is just a natural rock formation. It’s a lie they’d like to believe themselves. Monsieur Nerluc is, in fact, the lord of all tarasques, and strange cultists seek to waken him. If they do, his age-old toothache will begin to throb, and he’s going to be horrendously angry.
