Agent Westerling, I've been instructed to write this letter by two very helpful women by the names of Vendrask and Blake, declaring my presence to you. The contract they presented to me made it abundantly clear that my former style may not be welcome in your organization, but it is also exceedingly obvious that you could benefit from my skills as a machinist. This letter, a formality though it is, serves well enough as my declaration of intent to serve the Spellguard by aiding in the restoration and replication of whatever Svirfneblin artifacts you deem fitting for my skills. In the meantime, I'll be waiting on your assignment, and trying not to sully the name of this illustrious organization too badly.
Stay safe, Hall
[Scribbled beneath] I guess that's Associate Hall now.
