Alien-like creatures with squid-like heads and mottled blue skin. They can be found in a small section of the Forbidden Woods, as well as the Upper Cathedral Ward. These small squid-headed beings are fairly weak, though they will try and charge you. They attack only with very basic slaps, shoves and flailing combos, but hit surprisingly hard for enemies their size and have extremely high defense.
There is another variant of the small celestial emissary that sprouts tendrils around its head, and will use magical homing attacks that can deal a great amount of damage unless you close the distance quickly.
When first entering the Lumenflower Gardens, there will be multiple small kin of the Celestial Emissary, a Great One, emerging from cosmic rifts of some sort among the flowers, which will attack in a large group.
