Ig

An ig with a lower-case "i" is a lizard-like reptilian-ish lifeform, (possibly short for iguana?), native to the planet Widdershins. They are small enough to confortably perch on the sholder of a human. They have a dumpy body with pink hair sprouting from a scaley hide, a snout and three pairs of legs.

Ig with an upper-case "I" is the particular ig which enters into a master-pet relationship with Dom Sabalos and which travels the galaxy with him in search of the fabled Jokers World.

There may be more - a lot more - to Ig than meets the eye...
