wayfarer's reverie quests across a year or more

  • So I discovered an active Wayfarer's Reverie quest and, over roughly a week and a half, finished it. The quest reward NPC won't appear until late August, so I can't turn it in yet.

    In the meantime I've been reading up on the Wayfarer's Reverie on the wiki, since I know nothing about it and don't even remember picking up that quest. So far I've learned that there are four quests, given during the actual Reverie in late August. Each of the four quests is repeatable, but can only be turned in once per account per year.

    I am interested in doing the remaining three quests. My idea is to pick them up this year, then, at a pace dictated by real life circumstances, take a year to complete them and then turn them in *next* year.

    My first question is, will the NPC this year accept and reward for a quest assigned *last* year?

    My second question is, since the quest was picked up last year, can I instantly pick it up again to then finish it for *next* year?
