Paimon is great scholar in his own right, in fact he may be the greatest mind in the infernal court. He has no desire for personal power, but he has amassed so much knowledge that no plan gets enacted that he does not know about. His familiars granted to mages and witches never fail to teach his subjects whatever knowledge they need to know. All he requires of course his their ever-lasting soul.
While he gives out good familiars he is never summoned himself. It is said that in order to summon Paimon the would be conjurer first needs to learn his secret language; no small feat. Then properly summon Paimon in this language and converse with him in it. Anyone that attempts to summon him will instead get his two chief advisers Beball and Abalam.
Paimon appears as a man with an effeminate or even a woman's face. He ride on a camel that breathes fire. He is richly dress and always appears kingly. He carries a rod that he uses to command or on the rare times that he partakes in combat.
If attacked Paimon sees fighting beneath him and will send his legions in his stead. If he found alone he will summon Beball and Abalam to fight for him.
All other Baalseraph fear him but they also value his sage advice and knowledge. None dare openly plot against him.

*For the record, while I have nothing against adding Lucifer to my games it seem far to Judo-Christian for my tastes. Especially when I can achieve the same goals using the D&D version of Asmodeus or Tharizdun.
