All of them!? Uh oh! Haha! Questions here! All of these couples are shared with @thesixthplaneteer so as always his input is always here too!
#29. What compromises are they making in their relationship?
Harrakhty + Parvati (Follower of Set and Ravnos from VTM)
Harrakhty is compromising his own political advancement within his cult, and is also putting true enlightenment on hold - or at least giubg at a slower pace when it comes to achieving it. While Parvati now is a staple within the temple, it was certainly a scandal way back when to take the Ravnos as his bride. Parvati makes no compromises to be with Harrakthy save for perhaps having to wear clothes... and eventually the torture of half-life pregnancy.
Ralph + Khloe (Thinbloods from VTM)
Ralph is making no compromises to be with Khloe. At most making the coterie dynamic ever-so-slightly awkward by two out of four being in an intense relationship, but otherwise he's breaking no oaths or being forced to do anything or whatever in order to be with her. To him, it's probably the easiest relationship he's ever had.
Khloe relatively is also making no compromises to be with Ralph. Her sire doesn't like him, but she's not exactly punishing Khloe for being with him. There's light meddling but otherwise - these two are easy going and happy when together. :D
Godwynn + Lyubov (Ventrue + Tremere from VTM)
Godwynn's compromise is complete surrender of actual power - he meets with Lyubov in a dreamworld, and while he gets to go full hog-wild in it, it's not REAL-real. She has all the power, and he has none. Only if they meet physically would he give her any real threat. Lyubov is doing this at the behest of her sire, but she also gets to taste a dangerous situation... which may not end pretty for her if she doesn't play things safe.
Derrick + Coral ("Human" and Triton from DND)
King Derrick is - as the title implies - a king, and having a foreign/"monstrous" wife could put him at odds with some of the people of his kingdom or foreign dignitaries. He essentially is compromising the stability of his rule for Coral's hand. Coral's compromise is being away from her people. She isn't barred from seeing them, but her people as Triton have a duty to protect Overlanders from Leviathan attackers, so they can't exactly come visit often. She is surrounded by love, but she is still an alien in this world.
Rosario + Damaris (Inquisitor + Rogue Trader from W40k)
Rogue Trader Damaris sacrifices profit, and will cut his own pursuits and adventures short were Lady Inquisitor Rosaria to call for him. He will bend a bit for authority, or give up treasure if she needed it. Rosaria is vulnerable for Damaris - the two knowing in another life they would probably be wed on some paradise planet away from these horrors... but duty calls. They live a life apart, sometimes seeing other people for a bit, living dangerously and without knowing for long stretches of time if the other is alright. When they're together though, passions are intense, but they can't stay long in one spot. Duty calls.
