The Ancients just couldn't leave well enough alone. They were always looking for ways to create the perfect soldier, or genetically engineer creatures that had human level intelligence but were capable of living and surviving in the harshest of conditions and environments.

Many of the creatures wandering the wastes are a result of this genetic tinkering (tampering) and although created for one purpose, have become something deadly to all those they encounter.

The Leviathan is just such a monster. Originally the Ancients had wanted to create a humanoid that could withstand the rigors of working and surviving deep beneath the surface of the oceans, and one that could heal quickly, as work in such environments were always wrought with dangers.

Things didn't go as planned (which sadly was often the case). This creature starts out as a virus that once introduced to a host (any genotype except plants, which are immune), causes the host to undergo a drastic change.

At first, the change is subtle. The host discovers that it can heal much faster than it normally would, even have previous lost limbs and digits re-grow in a matter of days. Injuries that would have taken months to heal are mended in hours.

After approximately six days the host then begins a very rapid and drastic change to their physiology and psychology. In less than twenty-four hours the hosts changes, taking on distinct aqua-life appearance. The skin becomes a mottled blue grey and very slick, while the head elongates and the lower jaw almost completely separates. The teeth become small, and jagged, with the exception of the front teeth, which become almost dagger like.

It grows in size, reaching ten to fifteen feet in length and weighs approximately 1500 pounds. It also then sprouts a pair of tentacles from the lower back. The legs become shorter and end in fins, while the arms lengthen and gain powerful rending claws. It grows a long powerful fluke like tail as well.

The most startling aspect of the transformation is that if there are any other hosts nearby, they have an irresistible urge to come together. When this happens, the two or more hosts actually merge, adding their own mass to the creature, causing it to grow an additional 5', and gains an additional 5 hit dice and the weight increases by 200 pounds per additional host.  This can cause the creature to appear to have even more limbs, tentacles and even un-transformed limbs and heads from other hosts.

Sadly, by day 8 any trace of the hosts original intellect, personality, memories and mutations
