Razorvine’s a fact of life in Sigil. A single plant can have from 2-20 separate vines, all linked to a common root system. Its leaves are small, heart shaped, and so dark as to be nearly black — they grow in dense clumps near the stem on wiry springs, but in fact the serrated leaves are completely harmless. It’s the triangular stems that are the real danger – easily slicing up an unaware cutter.
Razorvine is a curse and a plague for most Cagers: A cutter trims it back, poisons it, burns it — and it just keeps growing. Its diabolical twists and knots make it impossible to tell how many vines a cutter needs to slice to finish a plant off. Some cutters use the stuff when they set up “toll-stations” in dark alleys or the back streets of the Hive — it can grow several feet a day, so these turn-spike tolls can spring up overnight. Touts just talk about the plant and point it out to tourists, who are sometimes fools enough to try hacking off a souvenir.
Fact is, what a berk does with razorvine gives a cutter a pretty good idea of what kind of man he is. It’s useful as a sentry to keep unwanted intruders out of places they’re not welcome. A few animals can eat the leaves; the vine can be grown as forage for these creatures. In the last of its peaceful uses, it can be dried and used as firewood. In a more evil vein, it can be used as a whip, a binding rope, or an effective garrote.
