Alzarius

Alzarius is the homeworld of Adric. Its coordinates from galactic centre are 1001100 by 02, identical to those of Gallifrey. However, it resides not in the universe containing Gallifrey but a smaller universe known as E-Space. A starliner from the planet Terradon crashlanded an unspecified number of years before Adric's time. Although the inhabitants of the liner at that time believed it to be 'four thousand generations' previously, given the peculiar effect of the starliner on the ecology of Alzarius this figure is at best highly speculative.

Alzarius is most notable for the highly unusual biology of its lifeforms. This manifests itself most obviously in the form of extremely rapid adaptive changes made by Alzarian animal life. If placed in an environment it finds stressful or otherwise uncomfortable, an Alzarian creature will rapidly develop whatever characteristics it requires in order to render the environment less stressful, such as the ability to breathe in a different medium, or higher muscular density.

Connected to this is the ability to regenerate injuries at an accelerated rate (although this is less spectacular than the similar Time Lord ability). The rate of healing slows as the individual ages.

Alzarian biology is also unusual in that the boundaries between animal and plant forms of life seem less rigidly defined: the eggs of the Alzarian spider have been discovered developing within riverfruit, apparently as a normal part of the planet's life cycle.

It is unknown whether the unusual abilities of Alzarian lifeforms persist if they leave the planet. Adric never displayed any particular adaptive traits during his time with the Doctor but did display accelerated healing on at least once occasion.(DW: Full Circle.)
