[1x1] The Last Stand

Couldn't find an opponent. Went through a one-way portal, and there were 8 two-way portals leading to empty squares. Where is the opponent?

If you are playing against the AI, on the second week, both you and the AI hero will be automatically teleported to one of the arenas. You just need to skip turns until the second week.

In multiplayer, the teleport function works the same way. But if the players are ready earlier, they can teleport to the room through a one-way portal and choose one of the 8 arenas themselves.
