Asmodeus

Asmodeus is a devil's pet. After a unforgivable act, the devil took away their job in the underworld, forcing them to do work in the over world. Also known as surface work, contracts to fulfill offered by mere mortals. Asmodeus must fulfill jobs given to them by summoners. The Devil promised to return their job if they manage to collect a thousand souls. 

It's hard to get to know Asmodeus, rarely do they make a friend. They always seem to make more contracts than the do of a personal companion.  Asmodeus has a hard time trying to cope with emotions, the only emotions they seem to know their way around are the emotions that are associated with revenge. Yet, even then they aren't on the prickly side. 

They won't share any secrets with you about their demonic tendencies, for they are too afraid of a mere mortal knowing too much about them. They try not to open up as much, believing it's a sign of weakness. 

OTHER

Asmodeus, the devil of revenge and lust. Call upon him with your sacred text and they will soon be there to smite your enemies or satisfy your deep desires.

Asmodeus can only interact with people when summoned, other than that they cannot leave hell. Only people who summon Asmodeus can see them, as other beings cannot see into their realm. This means Asmodeus opens his 'world' to their master allowing them to see what they see. Asmodeus can allow other mortals to see them if the master allows them to.

They make deals, hard deals. A contract, you give something and in return Asmodeus will do your dirty deed for you. Whether it's your soul, first born child, your sibling. You name it, but it must have something of meaning. 

Asmodeus can't be harmed, or killed. The only way to kill this demon is with a blessed blade dipped on holy water, or killed by the devil himself.
