Summoning
To be able to summon one of the Tenochtitlan Spirits, the holder of the key must first allow blood to drip onto the head of the key. After that, a deep red magical circle will appear in front of the holder to put the key in, to summon the spirit. Allowing the circle to appear and not summoning the spirit will put you in bad terms with the spirit, sometimes making the spirits not appear when you actually summon them, unless you are in very good terms with that specific spirit.
