Fiction

Ask Vector Prime

Carillon operated notorious gaming pits which tempted many beings and commanded a vampiric horde of Omnicons. At some point, Vector Prime encountered her, an experience he never hoped to repeat. Carillon was therefore among many great villains who Vector Prime warned readers of his online Q&A column to hope to never encounter. Ask Vector Prime, 2015/09/30

Notes

• Carillon was one of many new characters name-dropped in the Facebook edition of Ask Vector Prime on the final day that Vector Prime ran his column as a multiversal singularity.
• Carillon's further background therefore remains unexplored, and it is unknown if she is even a Transformer. She wouldn't be the first non-Cybertronian to hold sway over Cybertronians.
• A carillon is a musical instrument comprising 23 bells, typically utilized in bell towers of European/Christian tradition. A revenant is a person who has returned, especially from the dead.
