Maskwyrms are a kind of chimera created by Hamilor, a Lemilonese geneticist. A maskwyrm has its body derived from a ray, sporting 6 flying limbs and an intelligent brain. Maskwyrms have powerful eyesight, good hearing, a good sense of smell and electroception, being generally sensible chimaerae. What sets them apart, however, is their natural power to extend its spirit into someone. That someone is usually its owner and tamer, and through that spirit, it may relay the information it has gathered.
The name for this creature comes from its primary purpose, it can be worn as a mask to help visually impaired people see. Of course, its use as a scout did not go unnoticed and the House of Law acquired the first few hundred specimens for itself before allowing commercial use.
