Rodrigo Del Monyo is a fictional character who is part of the Goldvane story arc. He is the head member of a spanish organization called Derribo, whose sole purpose is to eliminate all who were involved in re-retrieving the stolen designs from spanish hands and back into England's hands. In Memory's Truth, placed in 1748, he plots to assassinate Richard Goldvane.
Rodrigo carries a steel rapier painted black, nicknamed Demoledor, spanish for "Demolisher". This rapier is made of the finest steel available, and Monyo sharpens it daily.
