Well, that's just great. "...I don't know much about your prior experiences with magic, folk of Brancrug, but I can promise you that sigils, such as I used to accomplish this, are nearly the exact opposite in nature as what local lore I have yet encountered. They're safe, predictable, and repeatable; their nature is such that no matter your method of approach, you will find the same Sigil and the same spells. Though the initial derivation of them may deal with the analysis of stranger powers, they are works of man, through and through; they behave according to the will of man, not some strange power with stranger demands. They do exactly what they say they shall do, and they will do no further. Should I use the Sigil of Life to heal a wound, it will promote life and growth, and do naught else. Should I cast the Sigil of Vigor, it will sustain one's vigor, and naught else. That's something of a problem when you're using it to keep an army on the march, actually, but I can attest that a General who would sooner die himself than subject his men to needless risk trusted that Sigil for that exact purpose. I will not risk harming people who have come to me for help, not unless I've exhausted my options to help in any other way. This I swear upon my honor and my oath, and may the Justice I'm sworn to strike me down where I stand should I fail to keep it."
