Variegatus

Variegatus is the current ruler of the Admirabilis, ascending to leadership five generations after Ventricosus.

Variegatus is more child-like than her predecessors, perhaps due to the fact that she is most likely younger than Ventricosus when they each met Phos. At home, she was told that she was helpless and lacked the talents of her predecessors so she wanted to prove herself by venturing into the land on the surface that everyone else feared. Despite the legends told by her people about the dangers of the land, she approached it without much fear or apprehension. Despite her inexperience, she is an ambitious person who wants to go to the Moon to rescue the rest of her relatives.

Variegatus is a cheerful but forgetful person. When Phos asks her about key events of the past, it took her a long time of thinking before she remembered. Much like Ventricosus, she mentions that she liked the "beauties" found on the land, referring to the Gems.
