Guild Wars 2

To those who do not know what a Searing Cauldron is:
It’s a weapon of mass destruction used by the Flame Legion to lay waste to Ascalon in 1070AE. The very same Searing Cauldron can be found in the Iron Marches (source).

Now, there are at least 2 confirmed Searing Cauldrons in Orr (see the notes at the source above). If the Orrians had access to this kind of firepower, then why was the approaching charr army such a problem? As far as I know, the orrians were desperate just before it was destroyed by Vizier Khilbron. But with 2 Searing Cauldrons the Orrians had enough firepower to wipe out the entire charr race and they had more than enough magic to power them (I think).

Can somebody shed some light on this?

There are 3 which can be found around the Vizier’s Tower, and one seen during a personal story arc.

Those cauldrons were brought by the charr who intended to cause a Searing in Orr as well, they were not owned by Orrians – and they were never used by anyone.

I see. Thanks for clearing that up.
