" It took some time before he became aware of a faint shifting in power, a ripple of awareness, like a searching crystal, an eye opening in the earth beside them. They were not alone. The presence touched him, stirred in his mind. Male. Powerful. Gregori. You are well, my friend. There was that cool menace in his mind. They knew one another so well after all the centuries of standing together against all odds.
Gregori had not voiced it as a question, and Mikhail was shocked, truly shocked, that he could make contact. Raven and he were deep in the bowels of the earth. The sun was at its greatest peak, and all Carpathians were weak. How could Gregori accomplish such a feat? It was unheard of, even in the legends and myths of the past.
Your woman needs to sleep, Mikhail. Allow me to assist you.
Gregori was far away--Mikhail could detect that--yet the bond between them was strong. Sending Raven to sleep gave Gregori a semblance of power over her. Indecision. Did he trust Gregori? The power that Gregori wielded was phenomenal. For the mental well-being of his lifemate, did he do what no Carpathian would ever consider?
Allow me to do this for you, old friend. She will not survive this day, Mikhail. Even locked with you, her human limitations will overcome her desire to aid you.
And you can do this? Even at this distance? You can safely send her to sleep? Take away her torment? There will be no mistakes? Mikhail found himself wanting to believe that Gregori was indeed powerful enough to do such a thing. Gregori was their healer. If he said Raven would be unable to last buried within the earth, it only confirmed his own belief.
Yes, through you. You are the only person on this planet I have given my allegiance to. You have always had my loyalty. I count you as my family and my friend. Until your woman or some other gives me my lifemate, you are the only person standing between the darkness and me.
Gregori would never have admitted such a thing unless he considered the situation a dire emergency. He was giving Mikhail the only reason he could to reassure Mikhail that he could be trusted. "
