When Little Mara arrived the square...
"M... Mas... ter..." Dorian was on his last breath, he couldn't utter more words.
Mutilated bodies of vampires surrounded him. There was no one but Dorian, struggling to survive, moving his body on the floor, extending his hand.
Her crystal bloody tears came out little by little.
There are three situations in which a vampire sheds tears, but there is only one occasion where the Clan Leader Vampire can shed crystalline tears of blood.
When he witnesses the death of those who have sworn a blood oath to him. They called the relationship as a Master - servant.
The bond of the oath makes the relationship between the Clan Leader and the servant stronger. And if they killed unjustly and mercilessly the latter, whether or not the Clan Leader witnesses it, the crystalline tears of blood will flow.
She had transmitted the pain and disappointment Dorian feels in her heart through the bond to little Mara.
