Round 1 ends tonight, but seeing as there are still 4 unexcused duels to be played, I'll extend until tomorrow evening. Septimus and Zero still have until the 20th.
After tomorrow evening, I'll flip a coin for whichever of the 4 un-played duels are still unplayed, unless one of the duelists can prove they put more effort into getting a duel to happen than did their opponent.
