Much like his compeer, Connafex merely appears as a cat because it is easier for most people to understand and is actually an extradimensional being known as an omen. He spectates timelines alongside Siglex, feeding off the changes that happen in each one (or rather the concepts created by them). He particularly enjoys calm, meaningful moments, and everything quiet and subtle. However, he also quite enjoys sad, bitter endings to things, making him come into conflict with his compeer frequently. He tends to be a good omen, appearing before important, positive changes happen. He often comes across as tired and grumpy, no doubt sickened by his compeer's taste in change.
His height and size are completely redundant, as he can appear anywhere from the size of an actual cat, to the size of entire planets if he so chooses (though, it's more an illusion than anything). Multiple of him can also appear at the same time, as each 'cat' is actually just a 'head' of a much bigger, incomprehensible organism. He, like all omens, is completely ageless, as they exist horizontally adjacent to time (though, if he did have an age, he'd be older than the concept of time itself.)
