In this realm succubi have the power to bind men to their will (similar to a queen bee). This include the chads, who are an enforcer biomorph. They provide physical protection and genetics to the succubus and are the highest status servants. Brads and business-minded men can reach high status too if they bring lots of resources to the queen and will then also be allowed to provide genetic material.
The lowest biomorph tied to the succubus is the crab. Succubi hate the crab and treat it badly at all times. The sad crab orbits around the succubus and can never break free from the soul-binding. The succubus ony lets the crab orbit to boost her own ego and to occasionally take the crab's resources. The crab's mindset is like Gollum - just like Gollum hated and loved the ring, the crab both hates and loves the succubus. The crab talks like Gollum - he will be sobbing romantic about m'succubus at one minute, then be cursing her and wanting to kill her the next minute. Whatever the case, The crab never shuts up about the succubus.
However, all men can break free from the succubus soul-binding and transcend to a higher level. This is possible for all male minions of the succubus, even the crab. After using willpower to break free, latent magical powers are unlocked slowly. The highest tier of these men have never been essence-drained by the succubus and can eventually reach the rank of wizard.
I feel pity for the crab and hope they can become wizards.
