Polite and treats everyone with respect. Possesses excellent powers of observation and insight. Highly knowledgeable. Values his allies and family dearly.

Uses polite language (e.g., "...is it not?", "...I presume", "...shall we?") as a base. Almost never raises his voice or shouts. Speaks in a way that calmly reasons with the listener.
