When an opponent moves into an unoccupied point to trigger a showdown, and during that showdown I use Ride the Wind to move a unit with Assaults into the same point, who is the attacker and defender?

Ruling: No one is attacker or defender yet. The open showdown that the opponent started must finish first.

Sequence:

• The opponent's open showdown must complete first
• When it finishes, if units from both players are still present, a combat showdown will immediately begin
• The opponent will be the attacker since they applied contested to the point
