Overlord H - Snowball Earth, new events, another new character (Patreon)

The home of Cocytus, the snowball earth, is described like a vespiary with a roundish form and completely made of ice... This is what I have come up with after a few tries.

If you have been following the roadmap, you may have noticed that I am done redoing some of the core things and I am currently focusing on adding more music and sounds, as I am testing things, I have decided to add new events as well (which also means new maps and characters).
They will dot the playthrough you are familiar with, which will be quite seamless thanks to the new event indicator that I have added in previous releases.

Other than Cocytus and Momonga, there is another token of a newly added character... She does not appear in the anime but can you recognize who she is?
