So I want to get my exotic void sword and I did a bunch of quests and I just finished the quest were you need a lot of ability kills and you need 10 special materials. Then I got a quest that had something to do with arms day. Now the question is How do I complete that quest, When does Arms Day arrive and what is arms day.

Thanks in advance.
