I'm not given to airing my views on the BB, but this will be an exceptional occasion, and it will be my only message on this subject.
Nostradamus decided in his wisdom that he would take over Mercinae, and in the process take on the task of rebuilding the City to its former glory. The history of Mercinae was re-written to show that the City was to be rebuilt under his watchful eye. A mere two months of Avalon has passed before he gave up all interest, and proclaimed that Thakria would suffer without him. No doubt he will take up where Snowlock left off.
Opportunism is acceptable where the end result is good for everyone, but when it only serves to inflate the ego of one who has no consideration for the Land in general, then it is bound to have repercussions.
