Provided I'm not doing things with Renard, would people be interested in working on The Forbidden Path (last of the WotG Windurst quests) sometime in the evening of Sunday the 14th? The wiki overview is here:

The parts that are easier to do in a group are farming the Bottled Pixies and getting the cutscenes in Castle Oz[s]. If we can get a decent-sized party together, we may be able to do both by farming pixies from Yagudo High Priests, Knight Templars, and Sentinels in Castle Oz[s], which range from 77-79. They've apparently got the best drop rate. Also, we can clear out the area around the Writhing Flame at G-7 so everyone can get at least the first CS. If you can bring a testimony of your current job, then you can also get the second.
If we can't get a larger group together, then we can probably send a smaller group to Pixie-farm other areas. A list of what drops Bottled Pixies is here:
