On The Sands Of Edom (слэш)

“Alec!” Magnus drops to his knees next to him, his eyes wide and his hands fumbling as he tries to staunch the blood flow, magic sparking uselessly over his skin in failed attempts at healing.
And Alec hates hearing Magnus beg, hates hearing the tears in his former lover’s voice. He fixes his gaze on the man who only weeks ago he had dreamed he would marry.
“I can help,” Magnus promises wetly.
Alec forces a smile on his face, finally managing to still Magnus’ hands with his own. “You can’t.”
OR, the one in which Alec thinks he's dying in Edom and asks Magnus to pretend to love him one last time.
