Imps

There are many kinds of Imps, but most notably, Fire Imps. Almost all Imps are born non-sentient, they're creatures, monsters even. Though it's rare, sometimes sentient Imps are born. A sentient Imp cannot understand those around them, they do not understand the Imp language, which consists entirely of grunts and groans. Sentient Imps usually end up leaving home at a young age to seek out friends, or at least people to talk to.
