Primegnificent = Prime + Magnificent

Prime:

1. of first importance; main.

2. of the best possible quality; excellent.

Magnificent:

1. impressively beautiful, elaborate, or extravagant; striking.

2. very good; excellent.

A neologism that represents the Horatio well, I believe. One word that gets together "the primordial" and "the beauty", two traits that they love to claim to personify themselves. And the second meaning of each word: "excellent", gives a redundancy bonus, in the aspect of being duplicated, as well as clones.
