Apopha Fesssi

Apopha Fesssi is a Blessed female Lamia and the sister of Neela.

When you first meet her, she is stuck at the entrance of Amorous Hallows. She gives you a quest to bring her a female or futanari Titan with the Meaty Trait to pull her out. After she gets out of the way you can pick up the Keystone and open the Cockblock Gate to Amorous Hallows.
