Young Titanic and his twin grew up far from the kingdom, but came here
to live with their extended family upon the death of their parents. They
are descended from the first dynasty, in truth, although look more as if
they come from the second.

Titanic can't be called impulsive, but he isn't as methodical as his brother.
He tends to leave loose ends and to make things up as he goes along more often
than not, which isn't always bad. Sometimes his slap-dash methods actually help.
