> it appears as a duck to me
At first I avoided servitor creation because everyone I saw using them had created them so that they were an energy drain to them. The method I applied was to have it represent part of the user, that way it doesn't add any extra energy drain. Astrabot simply represents your own innate divination ability and shares the knowledge with others also using the same standard. All the servitors I've shared are like this. The demon guard creates an interface for your own ability to defend yourself. By making it into an "antagonist" it's easier to automate the work done by this part of yourself.
Past lives, when fulfilled also appear as individual beings, so I figured why not?
If you felt that the previously shared servitors aren't for you, it may be that no part of you can be manifested in that form. This assistant on the other hand is mostly formless, it isn't defined as having a specific body type. It appearing as a duck was totally unexpected, but would then be because you view this part of yourself as a duck, and the other servitors aren't at all duck-like.
