Suggestion: Circling Heart Brotherhood of Arms at 58–68 keys

I checked key histories and 33 didn't match up from AzwaD to ultralow, some did go straight to Killua though which is where some of the keys ultralow got went to

I'll much rather exclude this, if it turns out to be ~58 keys then hopefully it supports the range

Untrack, the SF Baker comes from Zol too?

Using near ID, suggests the 21 keys came from Walgreens but that's it
