Finally At Rest

During heavily-restricted PTR testing the only thing affecting the Finally At Rest progress was the The Big Dig: Traitor's Rest Weekly. One turn-in added 17%. When there's no other source, this will result in at least 6 weeks to complete the achievement and get [item=213134].

Update January 17th: Right now the progress seems to be bugged because it's no longer character-specific (obviously not intended, because progress is tied to new entries in Eadweards journal and we only see them once a week). This means, right now, you can shorten this down to ~6 hours (and even less for characters played simultaneously) by completing the The Big Dig: Traitor's Rest Weekly on six different characters.

This can be done if you complete the quest "The Big Dig: Traitor's Rest" (assuming there are other locations too but for the first week of the patch, it is Traitor's Rest), across multiple toons. Each turn in of a completed Big Dig event adds 17% to the bar, so if you don't want to wait 6 weeks and have multiple toons, you can get it done in as little as ~6 hours (10 minutes for each event, every x:30th hour), by doing it on 6 different characters.

So, the 17% I have in this achievement is from completing the weekly Big Dig quest? Or can I continue to increase the percent counter by participating in the Big Dig event every hour on the half hour? Heck, if I can only increase the percent counter with the weekly quest, it's going to rtake six weeks to complete this achievement on my main (I don't have five other dragonflight ready characters) :(
