Pandit is Lieza's companion and guardian. They have been together ever since he (I think it is a he) was a pup and she was a little girl. Lieza found him with a bleeding leg in the fields outside her village when they were young. She took him in and ever since then they have always been together.
Though Pandit is actually very gentle and quite intelligent, he is very protective of Lieza, growling and attacking anyone who harms her.
