Knights of Tezoth

For a man of his build, Lord Gitgood Flaveresence moved quite briskly and did not overindulge in transport such as carriages or servants' backs (contrary to the rumors spread by ill-wishers envious of his wealth). He arrived accompanied by his wife, children, the Knight of Justice and her two friends, the Knight of the Golden Tower and his loyal companion.

Wait, I don't get it — did they arrive in the capital as some kind of "organized convoy," or each on their own "transport" (just together)?

And another question: is there enough room on a horse/pegasus/wyvern/hydra for Emilia to seat Amalia with her?

You can ride in the carriage with the lord, or separately on your own.

Outside of battle — yes.
