The direction of Muru's curiosity is not entirely random either, as Aireona would claim that the little dragon almost seems to have something similar to morals. When it knows that Aireona is willing to follow it, it will often guide her to places were she can be of help, and it has never once led her to the aid of anyone undeserving or untrustworthy. It is really anyone's guess as to how Muru does what it does, but Aireona suspects that it may be quite a good judge of character, through whatever means it can sense such things.

Senses aside, Muru is a sweet hearted creature. It appears to enjoy being of help to others, and seems most comfortable close to those that it has learned to trust. Despite this, anyone who tries to force themselves on Muru will find it to be rather cold... this Mututtu chooses its own friends, and is definitely no one's pet to be stroked whenever they want.

Airy and Muru split up shortly after they met, and the Mututtu aparently spent some time wandering the universe before they met again just after Aireona was deemed full Sii'Tonaa. Muru had found itself trapped on a Siisakoo infested world, and it was only by Airy's memory of the Mututtu that it was rescued and was able to keep its life.

After this rather frightening experience, Muru appears to have decided to remain with Aireona. It is often seen with her, though it does still wander off on its own at times, and it has made itself a skilled guide to the Sii'Tonaa. In recent years, Muru has been made an honorary member of the Alliance, and it has proven itself to be useful ally and friend.
