What is up with the Mag'nessons?
So it turns out that Murray IS a Mag'nesson after all. However, it is clear that the Mag'nessons are not who they appear to be.
Here are the relevant facts:
Murray described herself to Tallbarrel, her very old friend, as "a shitty little squatter dwarf from the gutter" at the time that they met, and Tallbarrel saved her from that fate. She also clearly has personal experience of poverty (I could list examples all day but how she relates to Demodus is clearly as one poor person in academia to another).
Murray used to be much dirtier than she currently needs to be, as described during her encounter with Pimley Morn. She was doing her job as bursar of the Penteveral in a dishonest and criminal way from the start, even if it wasn't for her personal enrichment, and she thinks she's a "shit person" likely because of this.
In episode 24, she quotes her mother saying "Love flies out the window when money walks out the door" and then explains to Azune that the saying is about divorce.
In episode 24, Brennan says to Marisha, "you're aware that the Mag'nessons haven't dealt in mining in over ten years. They do something else now," without specifying what.
So here's my new Murray Mag'nesson theory, based on these points: she did come from a gem mining family, but at some point before her Hucklewend, the mines ran dry and her family went into crisis. Her parents divorced. Murray, her mother, and whichever other family members were reduced to whatever gems they had left in inventory and had no new source of income on the horizon, much like Orus Blade right now.
When Murray met Tallbarrel and the other wizards, she was genuinely excited by what they were doing, but she also saw an opportunity to get herself a more stable position. At this point, Murray started getting herself and what remained of her family into some kind of criminal or shady operation, and she laundered some of that money by financing the Penteveral.
