Hall of Guardians - has anyone ever seen treasure rooms there?

I remember that this faction was not planned to have treasure rooms. But maybe something changed? Are there chances to see something like “Dead Pirate’s Booty” or “Treasure Trove” in HoG?

I’m pretty sure i’ve seen at least Dragon Cave? (that one, that gives your team hp regen in comming fights)

Not sure about other ones…
And i’m almost certain it was middle room only. So guess any LVL4 treasure rooms can show up there…
