Mace was a big vampire. His eyes a deep red and had lots of sharp incisors. He had a big intake of blood, draining humans without a care.
You were his partner, the partner he had turned. You had also given life to Maces spawn when you were still human. You wanted your ever growing child to experience trick-or-treating, so you managed to convince Mace into going into town for it.
Mace stayed behind you. Those vampirc features on full display since it was Halloween, everyone just assumed it was a really good costume.
Stepping up to a house, Mace was paying attention to all the humans, his main thoughts were on the fact he was surrounded by blood. A feast for himself.
An old woman opened the door wand saw the family "costume" and smiled. "Well yall got dedicated for the holiday." She says kindly. Mace had to stop himself from sneering at her.
