If you were an adventurer, would you not like all of the help that you could get your hands onto? Any sort of advantage in combat, reconnaissance, utility, chores....and possible bodily needs too, would surely come in handy, right?
Luckily, there is way to gain all of that along with any sort of skills, knowledge and gear you have already in your possession. It so happens that recently you found a spell/item/ritual/innate power/other method to help you with this (with or without your prior knowledge) that has the ability to summon feisty, cute, sexy, powerful little imps to aid you out in various ways.
Of course, there might be various costs for this sort of power, depending on what we plan out. However, there are plenty of fun adventures to be had along with your otherworldly companions.
The overall premise is simple:
An open world fantasy setting where you play one or even more adventurers who goes about doing various missions, quests and exploration, with the addition of multiple imps to help out. Plenty of minor and bigger stories we can jump into and complete in the ways we like.
This means that several adventurers can team up with us
