Carmacides, Clamacidés, Emacides
The baptismal name of a knight who served the first King Nascien.
His hand was sliced off in a battle against King Tholomer of Babylonia, but it grew back when he touched the stump to a cross on King Mordrains’ shield. Witnessing this miracle, Climachides, Nascien, and Mordrains immediately converted to Christianity.
Climachides followed Joseph of Arimathea towards Britain, but was unable to cross the Channel because of some unspoken sin. Nascien later brought him across in a boat.
