How does destroying a wormhole make Fostrow dishonourable?

Many destroy our shrines all the time, yet we allow most
of your wormholes to stand without any resistance on our
part. The difference being that the shrines are monuments
to the Gods, and while I am not sure, I am confident that
the wormholes have no greater purpose other than to be a
channel for snakes and serpents to transport themselves
and wage war on others. That particular shrine has been
used against me at numerous times in the past by a certain
female snake who likes to vortex me into Ashtan. Fostrow
destroyed it for the same reason that you destroy our
shrines.
