A friendly black panther (who introduced themself to me as Bagheera), after a while of getting to know them, was willing to help me create a servitor based on them as my first servitor for the public. I have a private version, this version is made as similar as possible, but for other people!
To those who can see spirits and servitors, Bagheera will manifest as a large black panther. They are fairly mysterious, but kind and wise. Their humor is refined, but still fun, and their speech is eloquent and flowing. Bagheera will protect you, be your friend and ally, and do what they can to help you get stronger, physically, mentally, spiritually, magically. They have relative free will and can agree and go with or resist and refuse as they see fit, unless specifically verbally commanded, so Bagheera's personality can shine through! You can command them to go learn something, and they'll do so to the best of their abilities to your specific instruction.
Bagheera can be a quiet though very pleasant companion!
