Basilisk

Markham hills are infested with two different breeds of menace - basilisks and ogres. The latter actually have a tradition where on the summer and winter solstices they go out, slay a basilisk, drag both the beast and its petrified victims to their hillside homes, and then feast on the flesh as it slowly unpetrifies. The locals know not to go out on these days, lest they encounter one of the many ogre hunting bands, but strangers passing through the hillside may be in for a nasty surprise...

The king's son got a ferret as a pet. The pet ferret went out into the woods, and dragged back a basilisk egg. Unfortunately, it appears not to have eaten it, as there have been several reports of petrification in the castle dungeon, but nobody seems to be able to pinpoint the location of the juvenile reptile's lair. Luckily, the king is hosting a group of monster hunters, and it would be quite rude of them to refuse him help in this time of need

The Stone Lady is a powerful medusa noble, whose domain lies between two rival kingdoms. Unfortunately for them, most spies and other such disreputable folk who need to avoid official routes have no choice but to go through the Lady's domain. While she herself isn't necessarily going to murder or petrify any intruders, her lands are littered with all sorts of stone-related monsters, most notably the largest known Basilisk, a monstrous reptile known as Ol' Lockjaw.
