Incubi and succubi of Clan Daryil mostly feed upon the emotion of lust. However, it may at times be necessary to send a lone agent out into the field, which means they'll have problems getting enough of that emotion.

For this reason, Lord Daryil has designed companion robots to allow their members to let off steam while isolated. These are based on the cyber-jaguar AI systems, but with the sex drive activated. Basically, an android frame with a latex catsuit as skin. These androids are fully sentient, since they obviously have to be able to have emotions to feed off of.
Exactly why they resemble anthro dragons, only Daryil can say and he's not telling.
