“In the darkness you will face fearsome creatures. The Vespera has begun.”

The urban fantasy Bologna in which the events take place was shaped by two divinities: Primo, a stable entity known as Veltha, and Secondo, an unstable entity also known as the Nameless Twin.

Frustrated by Secondo’s instability, Primo kills his brother, believing he is getting rid of him permanently, but from the remains of his body the Symbolas are born, heroes endowed with psychic powers, unaware of their fate.
Our heroes will have to defeat the Lucis, creatures
born from historical statues and drawings of Bologna, in the event known as Vespera.
