Summary
"The haggard spectre of a woman grips her hair, leaning against the warped and blood stained wood, eyes clenched shut and heaving.
Cracks and snaps come from the table as Astarion fiddles. There are footsteps and the groan of rotting floorboards as hands reach up, a warm cloth dabbing at her face. A tut as her jaw is tilted upwards.
The drow painstakingly cleans the captain's hands, still embedded in filthy hair before Minthara's urging bids them unlock.
Perhaps it could be called love."
OR : Semi-Nudist Durge and crew go looking for a Legendary Item (TM) out in the Bermuda, and there are more fucked up things than just the Dark Urge out there.

Summary
All those commitments that were all too easy to get lost among drove him crazy, but he knew they would always have this. A safe haven where their hearts could beat in sync, creating a touching melody that was impossible to replicate. The serenity that came from being in Nam-gyu’s arms was indescribable, and Thanos didn't seem to be able ever to drink his fill. He wanted to stay like this for as long as possible. For eternity, maybe. And then a bit longer.

Summary
When Garth asked Jason what phrases he wanted translated, the mer hunched down in the water and blew furious bubbles before huffing, “No.”
Garth frowned. You already know how to say that. What other things do you need to be able to say to Bruce and Alfred?
Of the speech, Bruce recognized his name and maybe Alfred’s. It made it feel like something was clawing inside his chest, knowing that he couldn’t communicate properly with this child living in his pool.
Jason curled his lip back. I know human words.
You really don’t.

Summary
At Hogwarts, Remus Lupin has a secret deeper than anyone suspects. He's not a werewolf, but a merman, cursed by a mysterious magical pool as a child. Every full moon, he’s pulled to the depths of the Black Lake, where transformation is inevitable, painful, and isolating. Only Lily Evans knows the truth, having uncovered it by accident years earlier. She has kept his secret and helped him manage the toll it takes on his body and spirit.
Now in their fifth year, Sirius Black starts to notice things: the way Remus disappears, the darkness inside he tries to hide, the excuses that no longer make sense. When Sirius follows Remus one night, he finds more than he bargained for. The truth is stranger, more magical, and just a bit more heartbreaking than anything he imagined.
