The Forest Ridge's eastern marches are protected by a
chain of colossi half buried in the jungle, great statues
that anchor an ancient primal ward against defiling magic.
Halfling shamans say that their ancestors created the
ward to safeguard their homeland from the ravages of the
Cleansing Wars, and that to this day the defiler kings of
the lowlands cannot defeat it. If the ward still functions,
it does not appear to prevent typical defiling magic from
working. However, defilers in the Forest Ridge often find
that the jungle turns against them. Savage predators,
carnivorous plants, and deadly snares beset those who use
defiling magic in the Forest Ridge.
