Like almost everywhere, Lake Maninjau has a story and, like most, it&rsquos a love story. It&rsquos about a time when Lake Maninjau was an active volcano called Mt Tinjau. In a self-defence competition among villages in the area, a boy named Kukuban fights a boy named Giran. Kukuban&rsquos sister Siti Rasani and Giran fall in love, and when Kukuban unexpectedly loses to Giran, he and his eight brothers decide to teach Giran a lesson by breaking up the romance. They catch the lovers meeting in a hut in the forest Rasani has lost a lot of blood from leech bites, and her brothers accuse Giran of besmirching her honour. The lovers are blindfolded, paraded in the village and taken to the active crater of Mt Tinjau. They pray to the gods if they&rsquore guilty, they should die horribly when they jump into the crater. But if not, the mountain should melt into a lake and Rasani&rsquos nine brothers should be turned into fish in that sulphurous lake. As the lovers jump, the mountain explodes and collapses into a caldera, and the brothers meet their finny fate. The villages around Maninjau lake are all named after characters in this legend, and it is said that the fish in the lake are the descendants of the nine brothers.
