YOUR OC and MY OC are going to duel. variations of this scenario can be:
ii.a, the spar: both of our ocs are training, and decide to spar each other as practice in the empty training grounds (this can take place during early morning or in the late afternoon).
ii.b, the colosseum: both of our ocs are pitted against each other, forced to fight for the amusement of the public. when one looses, does the other character gloat, or do they go to them to check up on them?
ii.c, revenge: one of the ocs challenges the other to a duel due a disagreement/betrayal/offence/etc. this can either take place in private, or in front of a crowd.
