Neverwinter Forest but you're still dead

Her eyes might've been glowing with joy at this. She didn't know. But Eldritch lovingly took the small albino ungulate in her teeth regardless, taking it outside and to a raised rock surface conveniently not too far from the tree. Here, she softly placed the white Deer and raised her head to the darkening skies. Rain was definitely right around the corner. 

"Tonight we call upon the Daedra! Mephala, Sithis, hear us!"

Dramatically, thunder and lightning rumbled overhead. The lightning cracked almost web-like, a blink of a spiderweb before it faded into the inky clouds and thunder. 

Eldritch's breath hitched with giddy excitement. "We offer you this fallen beast, that you, Sithis, may take it into the void, and return its soul to the web of the Night Mother, Mephala!"

The storm continued to growl and purr, almost as if pleased. 
And the rain came down heavy then, lightning cracking as Eldritch peeled open the chest of the deer and took out the heart, placing it on top of the snowy fur of their find to let the blood run down, as if a macabre candle on a corpse. 

The darkening blood seeped into the fur and down, running over the rock into the soil below, where then the thunder and lightning roared loudest, and Eldritch, hoping Mati joined in, raised her head further to howl with the storm.
