Reyes Magos
Both expeditions feature a Spanish Catholic Mission by the side of an Amazon tributary, run in 1909 by a sadistic, lone Spanish priest who beats orphan boys for any "pagan" behaviour, and in 1940 by a delusional Brazilian figure who believes he is the Messiah. He only trusts the visitors when he believes they are the Biblical Magi, but Karamakate wins his respect when he heals his wife. By now the children of 1909 have grown into disturbed and violent acolytes.
