Is it possible to have more than one edge battle occur on your same turn? If so, say for the second edge battle, what if both players do not have any cards to use for the edge battle, what happens?

It's possible to engage more than one objective on a player's turn, and an edge battle occurs for each engagement. You could also have an additional edge battle thanks to the Twist of Fate card.

If neither player has any cards to play into the edge battle, it is considered a tie, and ties go to the defending player.

That is what I figured but thought I'd ask just in case. Now to understand the rules, if there are no defenders, then the attacker automatically wins the edge battle and proceeds with next step in resolving the conflict which includes the unopposed bonus coming into place. I hope I got that right.
