Crisostomo Ibarra of the Noli Me Tangere, who, with Elias’ help, escaped from the pursuing soldiers at Laguna de Bay, dug up his buried treasure, and fled to Cuba where he became rich and befriended many Spanish officials.

He did not attempt to fight the authorities through legal means but through violent revolution using the masses. Simoun has reasons for plotting a revolution.
