While the Fungal Wind typically took five to six weeks to kill its host in its home Virtual, it grows more rapidly in the more humid environment of Nexus - this gives its host only three to four weeks of life. But the Fungal Wind of Nexus does not completely destroy the host's mind, turning him into a fully rational creature of death and disease. If he succeeds he is immune to all attacks of Fungal Wind, if he fails he becomes a carrier. The debate continues among Continuum members as to whether or not this is even a form of life. Either way, Shimmer Waves appear as bizarre, two-dimensional clouds of golden light up to a dozen meters in diameter.
Shimmer Waves wash over plant and animals, either accelerating or reversing the age of a creature.
Inanimate objects are also affected, but the Shimmer Waves are drawn towards living creatures. In fact some Waves have been known to immediately return to those it has passed over, reversing its own changes. The first form of the Keevar is that of a giant shark with legs to swim, the second is a very fast tyrannosaur creature that uses it arms to grab prey, and the third is a large winged harpy-like beast. The Keevar will shape-shift throughout combat in order to frighten and confuse its prey. Keevar always travel alone, except during the mating season when huge flocks will gather for an orgy of breeding.
