Normally I don't get too involved with the others schemes, but I'll tell you this Free; the demon in the Infirmary could be kept at bay with the help of some of the runes from it's healers, but unless someone with strong elemental magic comes along, those runes won't keep the demon at bay for long. Wouldn't sit well with Alaria to know that she failed to protect that precious baby twice, would it? But that is, ultimately, up to you.
