Among the rejected suitors there was also Lavinto, king of Tuenno. Proud and arrogant, Lavinto could not accept the fact that he had been rejected and he continued to woo Queen Tresenga, as he was convinced that he would manage to make her change her mind. However, neither the queen, nor the people of Ragoli, wanted this marriage so, at the umpteenth refusal, Lavinto lost his patience and, together with his army, marched against the small kingdom.
The people of Ragoli loved their queen and took up arms to fight against the invading army. Tresenga herself wielded a sword and drove her men against the enemy. The two armies clashed along the shores of Lake Tovel. It was a fight to the finish. Lavinto’s cruel, battle-hardened soldiers had the better of the queen’s army. Tresenga herself was killed and fell on the shores of lake. Her blood seeped into the waters of the lake and from that day on it became red, to remind everyone of the brave woman’s sacrifice. Some say that Tresenga’s ghost still lingers along the lake shores and that, on full-moon nights, she weeps for the sad fate of her people.
