While Zayren and I were messing around exploring in Pre-Searing Zayren pointed out that the effigies weren't on fire, and that they were all pointing in a certain direction. We later figured out that nearly all of them point to the Searing Altar. While there isn't an exact shape like I was hoping the dots still do connect.
Take this pic,edit it,change it,see what you can make of the dots. Also,so you can know what directions they pointed I shall provide that information.
The first one in the left corner,south.
The one nearby it,southeast.
The one below those two,south.
The one to the east below the altar(big blob of black),is pointing directly north to the altar. Well,actually,maybe northwest.
The one north of the last points south towards the altar.
The one farthest east points west to the one mentioned above.
This may tell us how they performed the ritual to hit just the Ascalon area or it may prove important for something else. Other than that it just seems like this is fairly complex for the Charr mages.
There were four mages guarding the Searing altar which tells us that it took alot of power or energy.This also means these mages may have died with the use of so much energy for the Searing. There was a Necromancer,Monk,Mesmer,and Elementalist there.
How each of them contributed to the ritual I'm still trying to figure out. Though I think the fact that Charr were near each effigy means that maybe they had to light the aflame all at once and the altar for the ritual to take place.
