You shall, first of all, be assigned a guard from the Fighters' Guild. You are at this time a double target, both a mage and a summoner, and no harm will come to you if we can avoid it. Make no mistake here: you will not suffer attacks, and you will have no need to attack anybody.
However, I believe you would do well to consider how messages such as this on the network are harming your peers in your Guild. Mages are not trusted as it is, in this moment, as we are being perceived as a threat. Your threatening people publicly, on the network, does nothing but confirm these fears. Reputations are laboriously built and easily destroyed. If the efforts of everybody in our guild to restore trust and mend frayed relationships are laid to waste because of a message such as this, I will be very disappointed indeed.
