Blood sacrifice is a custom in some cultures of the known world in which living creatures, sometimes including humans, are ritually killed to appease gods.
Rituals
Braavos
The Faceless Men of Braavos consider themselves to be instruments of the Many-Faced God[1] when they assassinate targets, believing they are giving a gift to those marked by their god.[2]
Priests of Aquan the Red Bull in Braavos sacrifice a pure white calf every thirteenth day and offer bowls of blood to beggars.[3]
Ghiscari
Pit fighters killed in fighting pits are considered blood sacrifices to the gods of Ghis by the Ghiscari.[4]
Iron Islands
As part of the Old Way, followers of the Drowned God can drown adversaries as sacrifices to their god.[5][6]
Old gods
Blood sacrifice was performed in the past by followers of the old gods,[7][8] with entrails hung from the branches of weirwoods.[8] The Skagosi are rumored to still sacrifice humans to their weirwoods.[9]
Pentos
The Prince of Pentos, chosen from the forty families of Pentos,[10] can have his throat slit as a sacrifice to the city's gods[11] during a famine or after a lost war.[10]
Qohor
Daily blood sacrifice is made to the Black Goat of Qohor. Usually this is through animal sacrifice, but condemned criminals are instead used on holy days. High nobles of the city might sacrifice their own children in times of peril.[12]
R'hllor
Some red priests burn humans as sacrifices to R'hllor, the Lord of Light.[13]
Sothoryos
The Sothoryi are said to be cannibals or ghouls who worship dark gods with obscene rites.[14]
Thousand Islands
The people of the Thousand Islands allegedly sacrifice sailors to their squamous, fishheaded gods.[15]

Quotes
Davos: I want no part of you, my lady. Or your god. May the Seven protect me.
Melisandre: They did not protect Guncer Sunglass. He prayed thrice each day, and bore seven seven-pointed stars upon his shield, but when R'hllor reached out his hand his prayers turned to screams, and he burned. Why cling to these false gods?[32]—Davos Seaworth and Melisandre
The Lord of Light cherishes the innocent. There is no sacrifice more precious.[26]
I have heard your arguments so often I could plead your case myself. Shall I? The fighting pits have been a part of Meereen since the city was founded. The combats are profoundly religious in nature, a blood sacrifice to the gods of Ghis. The mortal art of Ghis is not mere butchery but a display of courage, skill, and strength most pleasing to your gods. Victorious fighters are pampered and acclaimed, and the slain are honored and remembered.[4]
Davos: What gods do you keep?
Bartimus: The old ones. Me and mine were here before the Manderlys. Like as not, my own forebears strung those entrails through the tree.[8]—Davos Seaworth and Bartimus
