Cliffthorn
Cliffthorn was a poisonous plant that grew at the base of Highmountain in the Broken Isles. The plant's twigs were covered with a black slime that stung to the touch and would paralyze those who were not used to it.
Cliffthorn was important to the Cliffclutch harpies as they lived in the thorn bush bramble or lined their roosts with it. They also chewed on the twigs to acquire immunity to it.
