After having read the Usurpers' forums, a few comments.
First Fires From Afar were because we suspected BL was aiming for Const 8 and the Chalice which we could not give you. So, when you started reaching 2800 research (8th level) and we clearly saw we couldn't reach you, we decided to try killing your mages. We saw a Kinnara when everything was ready for the Fires so, obviously you were not aiming for Const, but still decided to fire.
The latter 10 casts were just a demonstration of power after you have officially declared war by attacking Jotun capital siegers. I saw BL lost a lot and hopefully Mictlan and Pyth lost something too. We were planning to summon elemental kings but decided to hesitate with it
In the nearest two turns we were planning a massive teleporting attack on a death spec province you conquered with cutting off retreat and after that - a fortress there with a Blood spell so that you could not retake it.
