Concordia: Roma / Sicilia

No. Each land colonist’s first move takes it through a gate of your choice to a route just inside the city; land colonists can never leave Rome afterward (p. 1).

A sea colonist can move to any later space on the ship track for one movement step, but it can never move backward. Each of your sea colonists can move only once per turn, and only one of your sea colonists may move to Byzantium per turn (p. 1).

No. Entering either space lets you immediately build at most one house there, for the usual cost; you can’t build another there later unless you move to that space again on a later turn (p. 1).

You immediately score one god of your choice using normal endgame scoring for that god; if another player has already marked that god, you score half the points, rounded up. Each player can score each god only once per game, and you need a house available to mark your choice (pp. 1–2).

A province with a volcano tile on its mini-map can still produce, but gets no province bonus; if its bonus marker is removed and the fiery volcano tile takes its place, it can no longer produce. A no-building marker prevents further house construction in that province, but colonist movement is unaffected (pp. 2–3).
