Nereids are aquatic fey with deep ties to water. They share some similarities with naiads, but they are not guardians and do not bind themselves to a specific body of water. Although they are primarily aquatic creatures, their unique ability to imbue their vitality into a supernatural shawl allows them to travel on land as well. A nereid must be careful when manifesting a shawl, however, as their life essence is bound to it, so it can be stolen or destroyed to threaten the nereid.
