With this mod, you can fight and bet for fights in the Vivec's Arena. Like in the the Imperial City Arena in Oblivion, there are apparent teams of combatants and scheduled matches. To start you'r journey, talk to one of the arena masters in their bloodworks about "Join the arena". You need to be at least level 10 to join. After joining, you can fight in rank related matches or against monsters. Just ask about this from your arena master and of you go!
