Creature Design - The Sea Dreamer Matron

Chromatic sirens are organized in tight familiar structures called shivers. These shivers are governed by one single shiver matron, entitled to the best spoils gathered by her huntresses. Surrounded by her weakly male mates, the giant matron is bound to rule over the other members of the shiver with an iron fist until a younger and stronger siren dethrones her.
