I'm trying to get us back on track with once-a-week updates, but now that you mention it... I'm going to just end the week on sunday and do my updates Monday, so I'll adjust the date a bit.
I think the tunnel plot is Zaangoria's. There was something up with some duergar being creating dragons from stone, but it wasn't very clear what was happening so far (I haven't read last week's post yet :( )
The clones was Rivellesk's plot. They got some old noble rising and walking around as if nothing happened and then found out there were some important people who have been replaced by simulacra. It is unclear how, it is seemed like a forgotten plot from the old empire. In the mean time, there is something going on at the Old Land's as part of the Eleven Marches that meets with the simulacra idea. At the moment, only ash copies of people have been found.
