Actually, Suville demanded Wayburg after Carelia got Skalk and gave away Ser'qea to Caergoth. The fault was at 1) Caergoth for demanding Ser'qea before all the terms of the agreement were fulfilled, 2) Carelia for quickly capitulating to Caergoth's demands, and 3) Suville for not being patient.
This all makes me sad panda. But then again, Suville i guess were not so intrested to send anything to frontlines from the beginning.
